Ok, so I've worked up an ultra accurate load for my savage 10fp using 25.5g of H4895 under a 68gr match hpbt with a cci small rifle primer, winchester case. I worked these up when it was cooler and had no pressure signs. Now that the weather is getting hot here in S. GA (last weekend was 95 degrees) I'm getting blown primers. No other signs of pressure just a firing pin sized hole in the primer. How heat sensitive is H4895? I'm going to back off just a bit to see if I can still get the accuracy without the primer problems. What do you guys think?
