'''.460 Rowland''' is a type of [[ammunition]] for firearms. It is classified as a <span style="color:#0000AA">'''(P)'''</span>istol caliber, and was originally designed for 1911 conversions.
.460 Rowland is pronounced ''four sixty Rowland''. The cartridge is named after its original designer, Johnny Ray Rowland. It is essentially a slightly elongated [[.45 ACP]]; the case length was increased by 1/16" inch(~1.58mm). This seemingly small change allows .460 Rowland to be loaded at up to near-[[.44 Magnum]] power. The use of a muzzle brake is more than recommended to tame the extreme recoil this cartridge can generate.
Although in real life, Johnny Rowland himself has stated it is safe to chamber and fire .45 ACP ammunition in .460 Rowland converted firearms provided that they are properly configured (recoil springs in particular; see [https://www.460rowland.com/faq/ his website's FAQ] at question 16), I do not recommend it and therefore, do not consider it possible to do so in the game, unless that firearm is a revolver (similar to a [[.357 Magnum]] revolver shooting [[.38 Special]]). GMs and players who wish to ignore this rule and make it possible are free to do so if they feel it would enhance their enjoyment of the game.
