Just started load development and went with a 75grain due to advice from Berger techs. With a 1-8 twist I can shoot the heavies, I have read varied barrel life as to how hot the load is. I did have the barrel cryo frozen ( 300 Below, inc) to slow throat erosion. Can't wait to dust a crow at 400yrds!!!
I wish I had access to some really long shots, only 400 max. around here.
