Ok, sorry I didn't mean to start something. I probably wouldn't change either if the FL sizing is working that well for your gun.
Maybe I had an oversized chamber or something because it seemed like I was trimming way more than I should, and the brass was stretching way more after the sizing than the actual fireing
That's when I tried the body die, and could bump the shoulder back just enough to cycle smoothly, then follow it up by sizing the neck. My problem then went away, accuracy tightened up, and brass stretch slowed way down.
That was in a factory barrel, but I've continued using this process with tight aftermarket chambered barrels and has always worked well for me. Just have to use the body die more often lol.
