Du har rett - kuler i .452 kan benyttes og da er utvalget bedre
Sakset dette på nettet om S&W 460 Magnum:
The cartridge is designed to handle .452-inch bullets, but will also handle bullets of .451- and .4515-inch diameter, which are the same as those designed for the .454 Casull. Incidentally, .454 Casull and .45 Colt ammunition can likewise be used in any .460 S&W revolver; however, due to the cylinder length and long bullet jump or freebore, accuracy is usually substandard. If these “shorter” cartridges are tried, be certain to clean the chambers before firing .460 cartridges, or cases will likely stick.
