[QUOTE="MontanaRifleman, post: 356448, member: 11717"] My number one pressure indicator is how well the brass holds up, specifically the primer pockets, but that doesn't help much at the bench when you are working up. I keep an eye out for ejector marks and flattened and cratered primers along with a sticky bolt. Every rifle and load seem to show signs a little different. With my 700 Sendero 300 RUM I sometimes see ejector marks a grain or so before I see other signs. Flattened and slightly cratered primers tell me in right on the edge and when I get a sticky bolt, that means back off. When I run a half grain below a sticky bolt, my primers are fairly flat with some very light cratering and an occasional ejector mark , but my primer pockets in my Rem brass hold up OK and my bolt moves freely. It's what I consider a "warm" load. There can be other reasons for sticky bolts, flat primers, etc. and it's possible to get over pressure and miss the signs so you need to be careful. Im my experience, my rifle has always told me when it was time to back off. Mark [/QUOTE]
