I did have issues with jams as I made the mistake of assuming that all I needed to do was re-crimp the rejected rounds on my single stage at home. That doesn’t take care of the bottom as I learned, yea I didn’t re gauge the rounds. Rookie mistake.
So I got a Lee crimp die and resized the 1000 rounds. Now I use the Shockbottle to go through the brass first. I then resized the brass on the new Lee undersize die. Got 95% to fit. Tossed the remainder, most of which is Sumbro crap. Will probably be going through my cleaned brass to get rid off all that junk.
