Frequently Asked Questions

What is 460 Rowland, and what guns does this ammo work in?

460 Rowland is a wildcat cartridge based on the 45 ACP case. It requires a conversion—typically a barrel, spring, and sometimes magazine modifications—for 45 ACP pistols. This ammunition is loaded specifically for 460 Rowland-converted firearms. If your gun is a standard 45 ACP, it will not safely chamber this round.

Is this ammo suitable for hunting?

Yes. 460 Rowland is used by handgun hunters pursuing medium to larger game, and the 255-grain hard-cast hollow point is designed to deliver deep penetration and expansion suitable for that purpose. Actual hunting legality and suitability depend on your local game regulations and the specific game you're pursuing—always verify compliance with your state or province before use.

What does hard-cast hollow point mean?

Hard-cast refers to a bullet cast from a hard lead alloy rather than pure lead, which resists deformation under extreme velocity. The hollow point is designed to expand on impact while the hard-cast core helps the bullet penetrate deeply and hold together even at the high velocities generated by 460 Rowland.

What's included in a case purchase?

One case contains 10 boxes of 20 rounds each, for a total of 200 rounds of loaded 460 Rowland ammunition.
