SWC bullets so reloads ?? PL is to low or springs to heavy . OAL of cartridge is to short or to long maybe even amount of crimp . I have a 200gr swc load with OAL of 1.235 that feeds in a number of 45acp kahrs 1911's ruger my friends or I have including a new commander with a 20lb spring . maybe you should let a more experienced 1911 guy give it a try . My wifes kimbers a running machine .
