Wondering how the process compares to working up rifle loads.
I tried 3 different powder loads but the real finicky part is getting seating depth and crimp correct. Because the 9mm headspaces on the rim of the case you've got to have a bit of a lip where the projectile is seated but you still want some crimp on the round. Too much crimp = incorrect headspace which is never good.
Some of my first loads were seated too short so they would flick up on loading and jam the pistol every so often which is annoying and embarrassing in the middle of a match
I had a load that worked well but shot high and I couldn't adjust the sights any lower so I dropped .2 of a grain off my load and instantly it wouldn't cycle so I went back to the original load and seated the projectiles a little further out which brought my POI down.
It's been a pretty steep learning curve but now that I've got the load worked out reloading is a lot quicker than rifle. I can load about 100 9mm's an hour and that's going relatively slow
