IMPORTANT INFORMATION ABOUT THE HEADSTAMP ON THIS BRASS: Due to limited supplies of brass, Buffalo Bore has begun loading +P and +P+ ammunition in brass that may not be indicated as such on the headstamp. Example: 9mm Luger +P+ ammunition may be designated as 9mm Luger +P or simply 9mm Luger on the headstamp.

Please note that this ammunition is not intend for use in some guns check below to check what firearms are approved for use with this load. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

Owner of Buffalo Bore Tim Sundles on Heavy 44 Magnum +P+ Ammunition:

ATTENTION:This new load is designed ONLY for certain firearms. They are as follows; Ruger Red Hawk, Ruger Super Red Hawk, Ruger Super Blackhawk or Vaquero, Freedom Arms Model 83, Taurus Raging Bull, Colt Anaconda and Dan Wesson Revolvers. Suitable rifles include T/C Encore, "modified" Marlin 1894 (see next paragraph), Winchester 1894, any rifle with a falling block action and the Handi Rifle. We get hundreds of emails asking if this load can be fired in S&W revolvers or some firearm other than what is in the above list. The answer is NO. The above list is all inclusive. If some shooters continue to irresponsibly use this product, we may have to discontinue it and that would be unfortunate as it is our best selling 44 mag. load and it gives great performance for those that use it responsibly however, as is always the case, irresponsible use of any product ends up penalizing responsible users.

What do we mean above by "modified" Marlin? Marlin (for an unknown, not well thought out reason) is using a very slow rate of twist (1/38 inches) on their 1894 chambered in 44 mag. Because of this slow rate of twist, the heaviest bullet that the factory Marlin will stabilize is about 270grs. Other firearm makers that chamber for the 44 mag all use a much faster rate of twist so that their guns will stabilize and therefore accurately shoot bullets over 300grs. Many folks today want their 44 magnums to be able to utilize the heavy 300gr. and heavier bullets - Marlin has not figured this out. If you want decent accuracy out of our new +p+ load in a Marlin, it will need to be re-barreled with a twist rate of roughly 1/20 inch. I re-barrel all my Marlin 1894's with a faster twist barrel. A 44 magnum that won't accurately shoot 300gr. or heavier bullets is useless to me.

This load brings a level of power to the 44 mag. that has never before been known.
