If they are based on the H&G 130 mold they will usually cycle well with about a thick thumbnail's amount of ridge sticking out of the bullet once you have found the max oal for your chamber with your bullet. I usually run 200gn LSWC that use the H&G 68 (Hensley & Gibbs model 68 molds) and using that criteria have no problem at all cycling the gun. Most of the bullet books have data on 185 LSWC and I have had good success with W231, SR4756, Trail Boss and Alliant BE-86 with the 45 ACP LSWC bullets.
