[QUOTE="Lefty7mmstw, post: 951953, member: 48043"] An interesting thing that I've heard of locally is the shoe test. It's probably more accurate than any primer or case reading as those are influenced by headspace and chamber dimensions and/ or brass softness. Take off your loafer (not a heavy work boot mind you:rolleyes:) and tap the bolt open with it. If it doesn't easily open with a tap up and a tap back; you are likely too high and cruising for trouble. Chronographs aren't perfect but they do give you a general idea what's happening as it takes a certain amount of pressure to do the work required to move a bullet to a certain velocity in a certain chambering with a certain powder. The more variables you introduce the less valid this premise is though. [/QUOTE]
