just got done loading 100 rounds for the 460 this afternoon. very very easy cartridge to load for. all your dies can pretty much be left set for 45acp except the case mouth bell and crimp. your seating die doesnt need to be changed nor does your sizing decap die. i loaded up 100 rounds under 11grain charge of hodgden longshot there is plenty of case capacity for max loads if you choose to go there. primer cci large pistol primers 230 grn fmj oal of 1.270. max listed load i have for that powder is 12grn. according to ccg the bullets will set back if you rechamber them multiple times. i took one round cycled it 10 times letting the slide slam closed no setback maintained 1.270. i currently have the 24# spring installed. factory ammo may differ. i barely bell the case mouths just enough to prevent bullet shaving. going to shoot it first time tommorrow.
