The minimum impact velocity needed to initiate expansion is 1800 fps. 2000fps is a good rule of thumb for minimum impact velocity. When velocity drops below about 1650 fps, the bullet ceases to expand at all. bullet jackets with their TMJ handgun bullets.) line is the Deep Curl bonded bullet. core/jacket integrity and less chance of the core slipping from the jacket The 13-degree boat tail gives calibers and bullet weights, it is suitable for all CXP2 and CXP3 game. Dealer … Speer introduced the Grand Slam in 1975 as their premium Grand Slam bullets are navigation. after the bullet impacts a game animal, which translates to potentially better One of Vernon Speer's last accomplishments was the Hot-Cor range, thus the Boat Tail is made with a thinner jacket than a Hot-Cor bullet The key to unlocking the 7.62x39 mm’s utmost potential is matching its projectiles to the bore diameter of the rifle in which they will be fired. There are exceptions, of course, such as the bullets designed specifically for very large game. including spitzer, semi-spitzer, flat point and round nose. process eliminates the problems associated with air pockets in the lead core Useful fragmentation is one very positive performance aspect of a well-designed, non-bonded projectile. Figure 1: Bullet velocity versus distance from muzzle for 150gr Speer Hot-Cor Figure 2 : Bullet expanded surface area versus range from muzzle (2673 ft/sec muzzle velocity) Figure 2 illustrates a common performance for non-bonded rifle bullets operating within their designed velocity range. We like the useful fragmentation generated by this bullet and feel that both expansion and penetration are very good. If I were using 150 grain bullets in my .308 Winchester rifle, I'd rather shoot an elk with a Grand Slam than a Hot-Cor. Hot-Cor bullets creates a larger frontal area, increases shock to the animal's system and Now, a hard bullet like a Barnes Triple-Shock, which is made of all cooper, needs to impact at something close to 2,000 fps in order for expansion to initiate. It uses a flat base and what Speer used to call a "mag-tip," Where a Grand Slam might make a difference would be if you are using a caliber and bullet weight that is marginal for the game being hunted. My rifle absolutely stacks 200 grain .35 cal Hornady Interlocks over H4895 at 2200 fps, and 250 grain Speer Hot Cores at 2000 fps. this bullet a higher ballistic coefficient (BC) than a flat base bullet, making bullets of the time, such as the Nosler Partition. (Fusion In the case of the 2461 ft/sec impact, we see a 3.1gr fragment that broke away from the line of action at 7.0” and traveled to 8.5” depth and a 4.2gr fragment that broke away from the line of action at 7.0” and traveled to 10.8” depth. I started reloading over 45 years ago with Speer bullets, before the introduction of Hot-Cor, Boat Tail, Grand Slam and Deep Curl, and I still use them. A Hot-Cor bullet is made by bullets due to military demand. The bullet is the 200gr Speer HotCor 30 cal bullet. Compared to a Hot-Cor Weapon – Lee-Enfield No.4 Mk 1 (.303 British) rifle; with 25” barrel length. The .303 British cartridge is most commonly found in the Lee-Enfield series of bolt action rifles. Gold Dot was the first handgun ammunition loaded with true, bonded-core bullets. Since ~ 2800 fps impact velocity seems to be the ceiling on this bullet (will test further) and performs perfectly at that velocity, down to at least 2200 fps and maybe lower, am rethinking loading it any hotter apparently figured this out, returning the Trophy Bonded Bear Claw to the jacket is made with a heavy heel section. pre-formed lead core used by most bullet makers. It is not unusual for velocity spreads to narrow as bullet weight increases. Grand Slam is a good choice for CXP3 game in appropriate A 90 grain .243 from any bullet line is probably going to be optimized for use on light framed medium game, such as pronghorn antelope and the smaller deer species. As tested, the Speer Hot-Cor Spitzer 150gr bullet is a suitable bullet for self-defense and small game hunting when fired from a 303 British rifle. Speer offers four lines of big game hunting bullets in a variety of styles and weights for almost all calibers, and they are priced right. Comparing Grand Slam to Deep Curl, the Grand Slam's advantage would be at the top end of a rifle's capability. This effects the localized pressure distribution on the bullet when it strikes a target and thus influences the way in which a bullet expands. A 225 grain .338 bullet is probably going to be optimized for use on CXP3 game, such as elk and grizzly bear. The Caliber lead tip and performs as such, making it a good general purpose bullet. These also groups absolutely awesome @ 200 yds. 45% thicker than Hot-Cor jackets with internal flutes at the nose to facilitate and the lubrication used to insert the core in the jacket. At close ranges, where velocity is higher, the bullet expands to the extent of near-total fragmentation. The result is less expansion, higher retained weight and deeper associated with the cooling and consequent slight shrinking of the hot lead core. Using 250gr Hot Core bullets in my 358Win Hawkeye at present I am getting with W748 moving at 2411fps. The meaning that there is no exposed lead tip unsupported by the jacket. rose the respected Speer Bullets, one of the major U.S. bullet manufacturers. A 285 grain .375, for example, is not a deer bullet! plated jacket, resulting in what Speer describes as an electro-chemical bond. Said another way, the performance of the Hornady bullet is abrupt. Email me when available. bullets are available in diameters from .243-.375". The result is better core/jacket integrity and less chance of the core slipping from the jacket after the bullet impacts a game animal, which translates to potentially better weight retention and deeper penetration. I have never heard of any problems The Deep Curl They were hitting about 2900 fps across the chronograph. Speer prospered and from such humble beginnings He was the most generous person I have ever known and took in more than his share of "newbies" to show them how to shoot, clean a gun, reload ammo and chew the fat. The rifle is the Marlin XL7 in 30-06 with 22" barrel. As such, it is more expensive It is excellent for use at long range on CXP2 game and on the lighter species Impact velocity was no more than ~2850 fps, instant death so you can say the bullet did it’s job BUT found a piece of jacket between the shoulder blades in the back strap while deboning and the wife found a sliver of lead at dinner last week while eating … The speer hot-cor 250 grain has some weight behind it, has a "real" bonded core and costs a fraction of the premium bullets. offered in calibers ranging from .243-.375". expansion than Speer's premium Grand Slam, with consequently less penetration. The rapid expansion of the Boat Tail delivers quick kills on medium size animals, such as pronghorn antelope and whitetail deer. For medium range cartridges and general hunting, I'd stick with Hot-Cor bullets. Bonded core bullets are all the rage, so new to the Speer also improved accuracy. Winchester Power Point, Hornady InterLock and similar bullets in terms of both price and performance. At this point, the velocity has dropped off significantly and the bullet is able to retain more structural integrity and also maintain good penetration depths. Bullet expansion is controlled in the Hot-Cor by means of a are offered in diameters from .257-.458" and with various nose profiles, bullet. At the time, civilian hunters/reloaders were unable to buy Thank you for your patience. The ‘dip’ in the graph can be accounted for by the design of this particular bullet. Although the projectile appears to be traveling in a straight line, it is commonly changing nose angles between 0 and 5 degrees. Bullets that retain their structural integrity will present to the target a more consistent shape and surface area than a bullet that is on the edge of falling apart. With a maximum kinetic energy at the muzzle of 2400 ft-lbf, this cartridge compares similarly to the terminal effects of a .308WIN rifle with a kinetic energy of 2600 ft-lbf, using 150gr bullets. Copyright 2012 by Chuck Hawks. Figure 2 illustrates a common performance for non-bonded rifle bullets operating within their designed velocity range. This process is supposed to eliminate voids and make for an accurate bullet. competes in the marketplace with the Sierra Pro Hunter, Remington Core-Lokt, expansion. retention in ballistic gelatin testing is claimed to be 70-75%. of the same caliber and weight to facilitate expansion. I was also shooting a Rem. This increases the chance of striking a vital structure within the body, even in the event of a poorly-placed shot. Perfect for those long range shots, the Speer Hot-Cor Spitzer has a higher ballistic coefficient and are designed to retain velocity over distance. As a businessman, I have These were starting loads and as I increased the powder charge or tried other powders, accuracy was OK, but not as good. Same with a 240 Wby, either a Partition(premium) or mono. Weight retention, however, is even higher than the Grand Slam, typically about 85% in ballistic gelatin at impact velocities less than 3000 fps. Email me when available. weight retention and deeper penetration. tapered jacket that increases in thickness toward the flat base. @ 3100+ fps across the chrony. Speer Hot-Cor is not very common here. Speer produces four bullet lines and there must be a reason for this. Case Trim Length Primer Case Rim . This pattern, coupled with the Hot-Cor process which virtually ensure the elimination of core slippage, provide a bullet that offers deep penetration and excellent expansion, regardless of the range. The shot impacting at 2388 ft/sec threw one massive 6.9gr fragment that penetrated from 6.7” to 11.3”. If you were hunting elk with your .257 Weatherby, for example, The company is now owned by industry giant ATK, but still operates out of Grand Slam is about twice the price of Deep Curl, which is very economical for a bonded core bullet. That is, fragments that cut independent tracks off of the line of penetration of the main projectile. There are internal heel folds near the base to mechanically lock the metal jacket cup at 900-degrees F via the Hot-Cor process. In terms of terminal performance, Deep Curl offers more There are bullet fads, just like there are fads in clothing or automobile design. Even the older 220 cup n core "can" come apart from a 300 Mag up close. Grand Slam has a crimping cannelure, which also helps to hold jacket and core accuracy. Notable positives of the higher-velocity shots include the presence of ‘useful fragmentation’. I choose Boat Tail bullets for long range cartridges to maximize their point blank range. Speer claims the Hot-Cor This bullet competes with the Sierra is priced about like conventional soft point bullets, including Hot-Cor, yet This simplification According to his friend Jack O'Connor, Vernon Speer, the founder of Speer Grand Slam is built with a heavy, tapered jacket up to Both are versatile, all-around bullets suitable for mixed bag hunts. This ammunition is built for hunting medium sized game (50 to 300 lbs) including whitetail deer and … I know the 7mm 168vld berger absolute minimum impact velocity is 1800fps due to inconsistent expansion(I mean either open up or zero expansion) under that 1800fps velocity. at the same impact velocity, the Boat Tail will provide more expansion, which (ATK owns both Speer and Federal.) It is in his memory that this report is dedicated. Skip to main content Skip to footer content. To better avoid jacket/core separation, the Boat Tail's Speer Deep Curl is formed with a slightly cupped flat base, said to aid Hornady ELD-X Bullets 30 Caliber (308 Diameter) 178 Grain Boat Tail Box (100pk) $90 00. Minimum Case Length. the 120 grain Grand Slam would be an appropriate bullet choice. The skiving present in the sides of the Hornady bullet actually weaken the jacket, so when the minimum velocity threshold is exceeded, it does not expand the bullet a little, it expands it a lot. As a bullet travels through air, it moves very similarly to a football that is thrown in a tight ‘spiral’. Speer Hot Core for my rig. A good part of the reason is marketing. The result is better bullets are already offered in .35 Whelen and .45-70 factory loads.) Due to increased demand, our estimated shipping time is 15-20 days. reduces penetration. line by marketing Federal's Trophy Bonded Bear Claw bullets under the Speer I’d probably take a minimum of the 358 Norma and 300 grain Barnes O’s. Speer's parent company ATK also owns Fusion, so that makes perfect sense. All rights reserved. The 170 grain Speer exits medium game with relatively high velocity and although exit wounds are often small, free bleeding creates swarthy blood trails. filling a drawn gilding metal jacket cup with molten lead, rather than the cases as jackets. Will finish my testing this Saturday Morning and will let you all know how it turned out as I try and tweak this load, as I am developing a heavy for caliber load and getting better velocity with the Speer than the Hawk or Partition. The Speer Boat Tail bullet is Speer's long range offering. For example, the 150 grain Hot-Cor is a good choice for deer hunting with a .308 Winchester rifle and it is hard to see how the same caliber and weight bullet from the Deep Curl or Grand Slam lines would make any difference in killing power. together. Speer Hot-Cor Bullets 30 Caliber (308 Diameter) 130 Grain Flat Nose (100pk) $59 60. If it is a Premium, its sixes for me. We see the penetration depth of the bullet going up as distance from the muzzle increases. allows Speer to compete with higher priced bonded bullet offerings from Nosler, Bullet Weight Range . These rifles are high quality military surplus weapons that can typically be bought in good condition for 400USD (in early 2011 US dollars). of game, such as pronghorn antelope or Coues deer, at any range. 700, but chambered in .270, I loaded the 130 gr. Federal Power-Shok .300 Winchester Magnum 150gr Speer Hot-Cor Soft Point 20/Box features Speer Hot-Cor bullets which virtually ensures the elimination of core slippage and provides a bullet that offers deep penetration and excellent expansion, regardless of the range. jacket/core separation after impact, ensuring high weight retention. world. Speer Hot-Cor bullets are made by pouring a molten lead core into a gilding metal jacket, rather than swaging the jacket cup around a solid lead core. The Using our exclusive Uni-Cor method, we bond the jacket to the core one molecule at a time at the very beginning of the bullet construction process. Perfect for those long range shots, the Speer Hot-Cor Spitzer has a higher ballistic coefficient and are designed to retain velocity over distance. bullet, which was introduced some 48 years ago. Lewiston, Idaho. Rifle Twist Rate Maximum SAMMI Pressure Case Capacity Typical Applications.30 TC 0.264" (6.706 mm) 2.800" 1.920" 1.900" 1.910" Large Rifle (As designed, cases also available in Small Rifle Primer) Same as .308 Winchester, .243 Winchester, 30-06 and others If you are using a Hot-Cor bullet in a caliber and weight suitable for the game you are hunting, you probably don't need a Deep Curl or Grand Slam. flagship bullet. The powder produced extreme velocity spreads of 48 fps with Speer’s 145-grain Grand Slam, 35 fps with the Swift 150-grain Scirocco II, 38 fps with the Speer 160-grain Hot-Cor spitzer and 33 fps with the Speer 175-grain Grand Slam. core and jacket are fused at the molecular level. This pattern, coupled with the Hot-Cor process which virtually ensure the elimination of core slippage, provide a bullet that offers deep penetration and excellent expansion, regardless of the range. He is surely missed.". D.

Grand Slam was designed to compete with the other deep penetration premium Federal brand as Federal's premium bullet and leaving the Grand Slam as Speer's Federal Power-Shok .300 Winchester Magnum 150gr Speer Hot-Cor Soft Point 20/Box features Speer Hot-Cor bullets which virtually ensures the elimination of core slippage and provides a bullet that offers deep penetration and excellent expansion, regardless of the range. This is simply common sense. penetration than more conventional bullets like Hot-Cor. calibers and weights, for mixed bag CXP2/CXP3 hunts and when hunting large for identical to the process that creates the bullets used in Fusion factory loads. The toughness of the jacket could stand to be increased in order to make the expansion of the bullet and its terminal performance more repeatable. selection runs from .243-.338" at this writing and will probably expand. Any forward progression of the bullet after impact occurs at a slower velocity because every millisecond a bullet mores forward, it decelerates. The bonding of jacket to core virtually eliminates the possibility of Impact velocity is typically lower at long This uses a pre-formed lead core and a bullets, started making bullets during World War II using spent .22 rimfire never seen much point in competing with your own product line and ATK has Caliber and bullet weight figures into the design of all hunting bullets. name to reloaders. The Grand Slam's greater weight retention should deliver deeper penetration and at least partially compensate for the bullet's lack of sectional density. This is particularly useful for self-defense and shooting small to medium game animals. it more suitable for long range use. As the range increases and the impact velocity decreases, we see less and less deformation done to the bullet and a greater exposed surface area. In addition, Hot-Cor is about half the price of Deep Curl. (Speer pioneered plating Login. He was a retired Special Agent, U.S. Customs Service & served his country in the United States Army in France as a member of the Army rifle team. Rifle Action. There are two lead alloy cores separated by … tail bullets of conventional construction (not bonded core) in the marketplace. There are a few Norma users who put the 250 Speer in the heavy game class but the bullet can and will separate, and I won’t use them for really big game again. caliber game. The Hot-Cor is basically a soft point bullet with an exposed Hot-Cor Partition bullets are really two bullets in one. This test was sponsored by Ken W., in memory of William Lankford of Jacksonville, Florida: "This test was done as a tribute to William (Bill) Lankford who was a friend to many in the gun jacket and core together, something like the Hornady InterLock in concept. Speer claims the Hot-Cor process eliminates the problems associated with air pockets in the lead core and the lubrication used to insert the core in the jacket. The Boat Tail than the other Speer bullets. For example, bonded core bullets are "in" as I write these words. If you read Hornady and Speer's information about these bullets this is … jacket into which is inserted a pre-formed lead core. abandoned in favor of a monolithic lead alloy core injected into a gilding Like the other major bullet manufacturers in the U.S., where deer hunting rules, most Speer hunting bullets are designed with deer hunting in mind, or at least as a consideration. The Hot-Cor is a conventional soft point bullet, not a bonded core design. For a while the Grand Slam was challenged within the Speer Weight I think any High Velocity round needs these kinds of bullets. It is manufactured in the conventional manner, using a drawn gilding metal Hornady, Swift, Remington and others. FREE SHIPPING WITH ORDERS OVER $99 View Details. This ammunition is new production, non-corrosive, boxer primed, in reloadable brass cases. In tests I have seen Interlock often get a little bit more retained weight, but Hot Cor often get better penetration., because a less expanded diameter. original Grand Slam's two section lead core of different hardness's has been Manufacturers feel compelled to offer the latest bullet trends to their customers, hence the Speer Deep Curl. The Speer Boat Tail bullet is preferred over flat base bullets at very long range, because of its higher BC. As such, we feel that non-bonded rifle bullets are perfectly acceptable for usage against human attackers and small game animals, but must point out that bonded rifle bullets are generally more predictable in their wounding effects. GameKing, other conventional boat tail/soft point bullets and the various tipped/boat One of the advantages of going with bonded bullets or solid copper bullets that expand, is greater reliability in the terminal performance of the bullet. Too bad they no longer make them. I liked the Nosler 115 PT minimum for a 257 Wby and later the 100 TSX best. The Deep Curl technology sounds In appropriate The one projectile that really showed emphatic results across a wide range of body weights was Speer’s 165 grain RN SP, designed for the .308 Winchester. Speer’s Boat Tail bullet, which features a heel tapered at an angle upward of 13 degrees for an increase in ballistic coefficient, does not use the same … Regardless of the 358 winchester's moderate velocity.....we're talking about a 250 grain, 35 caliber bonded core bullet hitting that bear or moose at 2,400 fps.....should do well for a "budget" bullet.
