I just started using a 1911 for action shooting sports. I have two 4 cavity molds for the 358311 already, and like the heavy bullets that I can make power factor with ridiculously light recoil. The bullets feed real well, and weigh out at 162.5 gr.. Lyman even had 9mm loading data for this bullet in one of their older manuals. Not all that detailed though. Seating the bullets to the depth that fits the magazine, I am right at the crimp groove, but the bullet base intrudes maybe, .060 into the case internal taper, and I get a bulge there, plus examining pulled bullets, I see a taper swaged on the bullet base. Most of the rounds chamber OK, but occasionally I get one that doesn't. The 147 gr bullets have a workaround for this issue, by beveling the bullet base.
Has anyone ever tried using a case neck reamer in the 9mm case, to clean out a little metal, for clearance in the cases for that last .060 or so. I see Forster and RCBS make reamers, but I don't know what their finished diameter will be. I could ream sized or unsized.
