So I’ve got a serious problem. I started load development with RL 33 and 195. I started at 85gr-87.4. I started seeing pressure around 87.1gr. My best consistent loads were at 85.2 with avg speeds 3050... gun was shooting great for 50 rounds... fast forward to resizing and loading same powder charge I’m getting extremely heavy bolt lift and I blew a primer. I’m using a new jug of RL 33. Would this cause that much of an extreme in pressure? In my initial load I stopped at the first sign of a heavy bolt life which was 87.1gr. Now at 85.2 I’m blowing primers and increasing FPS by 100+. Could a carbon ring be the problem? I don’t have a bore scope so I can’t look. How do you best remove it? Could the powder variance be that big? I’ve got a big hunt coming up first of November and I’m stressing this won’t be a reliable gun. Help needed.
