[QUOTE="EXPRESS, post: 1226834, member: 1441"] Sure I can agree that velocity isnt THE indicator of pressure/excessive pressure. And no, the R8 probably won't ever show symptoms of excessive pressure throug bolt lift, due to the camming action and therefore a leverage advantage. However the case heads are ok, no engraving and primers aren't flattened beyond what is a normal mild load. I just did my first temp testing and found that for this load I get about 2.6 fps of decay per 1C drop in temperature. Now to test from 2C to -20C to check that the loss of speed is linear even at extreme temps and tomorrow Ill lest for heat with daytime temps predicted at 34C (93F) or may even warm the ammo up to 37 to get a broader gap to test over.
