[QUOTE="cfvickers, post: 494637, member: 25488"] Most people would never know or even care. I really don't care. For practical purposes I don't shoot in temps much over 90. But this past summer I had just gotten the rifle and couldn't help myself. I blew a primer and crushed my ejector spring with a load that I had fired at 90 degrees safely. So I started experimenting to see how much difference I had at different temps above 90. I backed it down 1/2 grain and started watching primers and case stretching. Found that everything was kosher until it got to 92, at that point it would get wild. groups went south and pressure signs got significant. Wait till late afternoon or early morning and everything was well again. The load was my established max and unbelievably fast, and I was getting half inch groups at 200 yards, so I stayed with it and just stopped shooting in high temps. When the temps got high I went to a mild load with 4831SC that was also really accurate. Kept the hot load for hunting. [/QUOTE]
