All loads listed on the Hi-Performance and Handgun Hunting and Performance pages must not be used in any firearm that is not deemed safe by a competent gunsmith. These are full house loads and can be extremely hard on firearms not designed for their use. Damage to the firearm and/or shooter may result. If in doubt use the Cowboy Loadings for handguns and Standard Rifle loads for rifles. Please note any warnings located below the calibers on our WebPages. Also follow warning printed on the box. Since CPC has no control over how the ammunition is used or what type of firearm is actually used we extend no guarantees either written or implied to the use of these cartridges.
