I have several hundred reloads for my 1911's, that fail the plunk test in my Glock 21. Never had a problem with the 1911s. I mostly used factory in the Glock. Now, I would like to use my reloads The info is: Winchester brass, Winchester large primers, 5.2 grains of HP-38, and 230 grain FMJs from Precision Delta. The OAL is 1.262. Any suggestions for changing the OAL? Can I just re-seat and re-crimp the rounds, so they will plunk in the G21 barrel?
