Aside from the OAL, just want to know if the casing is thicker/sturdier than 45colt? Or, are they the same thickeness from rim to mouth?
Yes the .454 casull is thicker brass especially in the web around the primer pocket.The cartridge diameter is also held to tighter tolerance than 45 colt.piller wrote:The .454 is thicker brass. If loaded in a gun with a chamber tighter than the loose industry standard, the .45lc can be loaded to some impressive pressures, but still not to the .454 pressures.
None noticed with the 45lc brass I've loaded to beginning 454casull loads but I'm shooting it in an encore pistol & rifle.Travis Morgan wrote:The case wall on a .454 is tapered. If you trim them back to .45 Colt length, it's pretty obvious. When you load close to .454 levels in a .45 Colt brass, you start having case failures right above the web.
