[QUOTE="long ranger, post: 185200, member: 800"] I don't understand the "load hard" relationship with twist rate. I run 111.5 grs of US869 under 300 gr SMKs in my 338LAI, which propells them out the muzzle at 3065 fps and the rifle consistantly delivers 1/4 moa groupings. This is very close to the begiining of pressure signs. I am using a 9.4 twist barrel, which now has just over 1000 rnds through it with just the very slightest bit of firecracking starting to show up, which given the round count, to me seems pretty fair. Am I missing something? I am simply a custom rifle builder, NOT a barrel maker, so any insight here would be great. [/QUOTE]
