Just back from target shooting, I had reloaded 45 auto w/230Gr XTP's, O.A.L. of 1.25. at this length they worked fine in my S&W 4516 but would not load beyond one round in my friends SIG P220. What did I do wrong? or is the SIG just finicky that way. I used PMC 230Gr Rn for my benchmark for OAL. The PMC worked just fine. Thanks.
