[QUOTE="kb1035, post: 2294181, member: 15645"] From my own experience, I have not found primer condition to be a reliable indicator of excessive pressure. I know a lot of people use it, and reloading manuals discuss it as a sign, but I've had really flattened primers on mild loads, and normal looking primers on hot loads, even within a particular manufacturer's primers from the same lot. Same thing with the raised/unraised edges around the firing pin indentation. I don't have/shoot falling block rifles, so I can't speak to that, but in all my bolt action rifles, for me, the most telling indicator of high pressure is heavy or sticky bolt lift. When I am doing pressure tests, I know I've hit or exceeded my gun's max load when I feel a noticeable increase in the force needed to open the bolt. Sometimes it's subtle, but it's always perceivable. I'll be interested to see what others say too. [/QUOTE]
