[QUOTE="geo4061, post: 1118125, member: 81625"] I bought a rifle from a gentleman that lived and worked up a load at 6000 feet and 50 degrees. It showed no pressure signs and was very accurate. I shot 10 rounds. Three of these had some primer cratering, ejector mark, and stiff bolt lift. The other 7 looked fine. I am at 600 feet and shoot at 80 degrees. Should I back off the load or try cooling the ammo. This 300 RUM will probably hunt closer to his temp than mine. Remember this load shoots in the same hole. That is the reason for all this. [/QUOTE]
