In this case being a break action it's easy to set headspace so I adjust the dies to give .001" headspace measured across the back of the barrel. I don't have the notes from that charge but it would have been around 20 grains or so in a LC 5.56 case so that would be about 60-70% load density. The load I have in my notes for that gun which I found to be safe was 24 grains of benchmark for a 55 gr hornady sp and later went to 26 for a 40 grain varmageddon, both of which gave no pressure signs with the same lot of powder and primers and brass headstamp. I've shot quite a few pounds of benchmark in my savage and it my favorite powder. I honestly don't know why that load was so overpressure. I guess if there is another factor involved besides charge weight I don't know what it was. I loaded more the same day back up at the starting load and up and it was happy again.
