So I did my first batch of reloads and I noticed they weren't chambering fully. The bolt was stopping 1/4" early for most of the rounds. Some seemed to fully chamber. Also most of the rounds were getting jammed in the chamber so that I had to tap on the charging handle with a 2x4 to extract them. So I ordered some head space gauges. When I put the rounds in the headspace gauge, most of them seem to be flush with the top of the gauge. At most they are off by .002". I tried to caliper it but it's hard to get the angle right. My dies touch the shell plate when I'm resizing. Besides I'm shooting from the same gun so I shouldn't have to do a full length resize, or does that just go for bolt action? I ordered a set or Hornady dies since I'm using a Hornady press. I was using RCBS dies. At this point I'm not even sure where to look for the problem since the headspace gauge isn't showing me any problems. UPDATE: Also I just tried some spent brass and it seems to chamber just fine without sizing.
