We'll see what happens. For those of you that might be interested, I used nosler brass, H 1000 Extreme powder, and Fed Prem GM match large magnum rifle primers.

[QUOTE="chipperman, post: 539211, member: 31093"] I purchased a new Rem 700 sendero SF II in 300 Rum this spring. I had a friend load 4 different loads they all shot sub moa. I had my gunsmith put in a custom trigger adjusted to 2.5 lbs. I decided to shoot a new bullet, the barnes 175 gr lrx . It has a BC of.508 and being a solid copper bullet will not explode on impact. I had a Huskemaw 5-20 Blue Diamond Series scope mounted with Badger rings and an ACI, angle cosign indicator, so I can compensate for slope shooting.
