Hi guys (and gals),
I've recently casted some 129TC, specifically NOE HTC359-129-TC-CD4. After PC, I sized some to .357 and .358 to test out load accuracy. The .357 seem to be just fine, they chamber in my pistol and case gauge just fine. I move up to the .358, using exact same setup on press, and no dice. I've tried seating at different depths and crimping more. It will chamber in my pistol (P320 Xfive), but it is tight to extract. No marks on bullet or case, so I'm thinking that .358 is just too tight for this guns chamber. But I wanted to see if you guys had any input. Only thing I can think of is more crimp, maybe? I'm loading on a 650 with Dillon dies and mixed brass, seating to 1.110". Any other ideas?
