I tested out some 45acp I just reloaded, and I shot about 100-150 rounds. I notice that my gun is super filthy. I use w231 @ 5.2 grains, oal is set to 1.260 but varies 1.257-1.263. Does crimp have something to do with it? In my book is says little to no crimp, and I have a somewhat light taper crimp.
