RE: 45 ACP crimp with lead and copper plated bullets.
You may find that those shorter , 185gr.bullets will require them to be seated less in the case to acheive a better angle for feeding . As described above , is the proper method for maxOL. (I prefer them to be a hair less than extending to the end of the hood for max.)
If you want to see some good holes , try the Hornady match 185 or 200 gr jacketed semi wad cutters, if you haven't already. I used to shoot my hand casts of the 200 gr.swc bullet, but got tired of cleaning the bbl. and went to the 200 gr. JSWC and my Gold Cup just loved them.
