I see you will answer questions about Berger bullets. I've got a G.A.Precision 300win mag and I've just got some 215gr VLD.s and the 230gr Hybrid Tac OTM for it and have only loaded 12 each to see how they grouped at 500yds. Best I got was around 5 inches for 3 shots out of the 215gr and barely under 3"for 3 shots of the 230gr. Any advice, I'd would be more than willing to listen ;-)
I wasn't happy with those groups for I've shot a 1" 3 shot group with 200gr SierraMatch Kings and a 1 1/4" with 208gr A-max's at 500yds. I wish I could say I could do that every day but that is far from so. I know the VLD's are sensitive to jump so I'll work on them a little more later. 500yds is as far as we have to shoot around here, there are some places that have a 1,000yds but they are to far for me to drive to.
By the way, you have my total respect and gratitude. Thank you very much for your service.
Have a good'n Jesse
