[QUOTE="Wachsmann, post: 716576, member: 10429"] FYI... I went through the same issue with the 4831SC. I shot or loaded 51.5grns of the 4831sc. No pressure issues but only got 2778 to 2790fps on this load. At 52grns i was starting to see sign of pressure issues. bolt was getting tight and I have a few lapua brass with some loose primer pockets. not to bad but definatlly looser than the others. Also let me say I have a 24inch barrel. I was chacing the more volicity thing and relized I'm probally not going to get the 3000fps out of this gun. Well if its over loaded it will but I dont want to burn the barrel out that fast and destroy expensive brass. I'm now loading hybrid 100V with what is recommended from hodgens web site (49grns). Good news is my volicity picked up to 2844fps and for 10 shots of testing I had a ES of 10fps. 2844 was the middle average if i am looking at this right.
