This Ammo Inc. Ammunition is from the TML (Total Metal Coating) Ammo, Inc. Defensive line. Proven Jacketed Hollow Point projectiles deliver terminal performance tuned for self defense. Load-specific development ensures extreme accuracy and consistency for each caliber. Balancing velocity, accuracy, and recoil, the Ammo, Inc. development team carefully analyzes every load to help the ballisticians achieve the specific outcome of superiority. This ammunition is new production, non-corrosive, in boxer-primed, reloadable brass cases.

Barnes TAC-XPD ammunition is optimized for carry and home defense use. Loaded with the popular Barnes TAC-XP bullet it is designed to deliver top performance when it matters the most. The TAC-XP’s all-copper construction and very large, deep hollow-point cavity expand, penetrate and perform more consistently than any personal defense product on the market. Performance through bare gel, light and heavy clothing, car doors, plywood and automotive windshield glass is unmatched by the competition. TAC-XP bullets are 100% copper, making them safe for the environment. These lighter all copper bullets also result in less felt recoil in comparison to lead core bullets allowing the shooter to recover quickly without sacrificing terminal performance. Barnes specially engineered each load using low flash powders to produce almost no muzzle flash, ideal for low-light situations. Distinctive Techni-Crom plated shells feed smoothly from the magazine for reliability shooters can depend on every time. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

For those wanting/needing a lead-free, HEAVY 357 Magnum load, generating full power plus, here it is.

Below are real world velocities taken from my personal stock guns. The industry established use of long laboratory test barrels that give false high velocity readings is essentially misleading to the public who won’t be firing the ammo from a laboratory test barrel in the real world, where it matters.

• 2145 fps – Marlin mod 1894, 18 inch barrel
• 1583 fps – S&W mod 27, 5 inch barrel
• 1591 fps – S&W Mt. Gun, 4 inch barrel
• 1507 fps – S&W mod 66, 3 inch barrel
• 1448 fps – S&W mod 66, 2.5 inch barrel

You’ll notice the newer S&W 4 inch Mt. Gun, gave higher velocities than the older 5 inch mod 27 S&W. This is because of different internal barrel dynamics and chamber dimensions of the newer gun. In general, the newer S&W revolvers are made to tighter tolerances than those of 30+ years ago.

Due to the long-for-weight all copper bullet, the 357 does not have the case capacity to use a bulky flash retarded powder and thus there is a noticeable muzzle flash with this load in all the test revolvers, however the rifle shows no flash at all due to its longer barrel.

This load is the typical barn-burning, turbo charged, Buffalo Bore type HEAVY 357 Mag. load and as such, should only be used in revolvers made of all steel. It should not be fired in light weight, alloy framed or cylindered revolvers. Feel free to use it in ANY/ALL 357 mag. chambered rifles and all steel revolvers/handguns.

Our 357 mag. ammo adds more power than ever before to the 357 mag. This ammo is safe to shoot in ANY all steel 357 revolver – this includes J frames. This ammo is no harder on your gun than any other normal 357 ammo. Please don’t phone us and ask if this ammo is safe in your gun. It is, providing your gun is in safe condition for use with any normal 357 ammo.

We don’t recommend this ammo to be fired in super light alloy revolvers as bullets may jump crimp under recoil, but the ammo itself wont hurt these super light weight revolvers. These revolvers are simply so light that the recoil is severe enough to cause crimp jump.

The below velocities are offered so that you can see what guns/barrel lengths give what velocities with this new 357 mag. ammo. You’ll notice that new S&W revolvers with short barrels are often shooting faster than older S&W revolvers with longer barrels. The new S&W revolvers are very good and are made with equipment that makes them more consistent and faster than the S&W revolvers of yesteryear.
