[QUOTE="Alibiiv, post: 1940019, member: 69192"] There's flattened primers and.......there's flattened primers. A hot load will show a primer that is flattened out, an extremely hot (over-pressure) load "will" flatten the primer out and leave no space between the primer pocket and the primer, usually the firing pin imprint will crater and sometimes the machine marks from the bolt will be seen on the primer and the back of the brass. Primer flattening is a pressure sign, also blowing out primers is a very dangerous load as well as a sticky/tight bolt lift, that's a load that is working close to a catastrophic failure. If the primer pockets are getting loose after a couple of reloads, that usually is a sign that the load is a hot load. And..........every load, in every manual will/may not be compatible with every rifle. My son and I both have Ruger 77s in 35 Whelens, made by the same gunsmith, with the same reamer on the same machinery. One year we tried Superformance ammunition in our rifles. My rifle liked the ammunition, however my son's rifle blew out the primers on two rounds, we didn't try three and he doesn't shoot that stuff in his rifle anymore!! I do not use a computer program to develop loads, I reload for a .270 Ackley Improved, so started out with the maximum load for the .270 Winchester and worked up from there using the chronograph and keeping notes. I know the loads are close to maximum due to primers flattening out and also the primer pockets getting really loose after three reloads using Hornady brass. [/QUOTE]
