I have a 45acp revolver, a 25-2.
Clark Custom Guns [no relation] has been converting those revolvers for 12 years to be 460 Rowland.

I have some problems with the conversion:
1) I don't want my chambers lengthened for 460 brass, 45acp brass can do anything 460 brass can.
2) I don't want to run 38 k c.u.p in a cylinder with 0.063" chamber wall thickness

I can get more power than 460 Rowland with ~ 23 kpsi pressures, if I make use of the longer over all length possible in the revolver vs 45acp semi auto magazine.

I have a problem with that much recoil [ more than 44 mag] can pull the bullets out. So I cut down a 45 LC seater die do I could roll crimp 45acp and 45 auto rim.
