New to me SW 1911 5". I have reloaded and shot several hundred reloads using w231 5.0gr 230 Winchester FMJ oal 1.250-1.260 without any issues. I recently purchased 1000 "Carroll 230gn LRN bevelbase magnum alloy "match grade" cast bullets" and loaded it with the same w231 5.0g but to an oal 1.250. The first round loads and fires but it then fails to go into battery on the next shot...and even seems to require a really hard pull to clear (almost like its stuck). The shot caseing expells no issue, it seems that its the loading of the next round thats the problem. The crimp is the same on both rounds and the bullet diameter measures the same. These bullets likely were sitting on my local gun shop shelf for awhile (not sure if that matters). I only made 50 to start...what do the guru's of reloading think the problem could be? What should I do next?...pull the remaining 35 bullets?...recrimp...shorten/lengthen...HELP!!! I stll have almost a thousand of these bullets left.
