45 cal sizing
Quote from Reloader on April 1, 2016, 12:07 amHello all,
Granted I may be new to reloading, but I have reloaded 5000 rounds of all of the following...9mm luger,....40 s&w.....45 acp fmj......and 400 rounds of 223.
Now after loading 300 rounds of 45 acp/fmj I switched bullets to 200 grain XTP Hornady. Start running and the sizing die actually closes the dam round...thats right, takes it from .439 down to .435. I have adjusted the sizing die all the way down, even past bottom, and no luck, the .451 bullets all crush the casing when I attempt to seat them.
What the hell am I doing wrong? It worked fine for the FMJ rounds of 45 just yesterday?
Thank you.
Kurt

My loaded .45 rounds are visibly narrower between the case head and the portion of the neck holding the bullet; in other words, resizing to <.43X is not unusual. As long as the case is sufficiently belled (without over-belling, of course), the bullets can start sliding into/expanding the case neck as needed, avoiding crushing.
