Hiya Kevin,
I have the 12 LRP in 6.5creedmoor.
This rifle is not ,in my mind a hunting rifle, it's heavier than I would carry very far. I knew that when I bought it and have others that carry lighter in .260rem, 25.06.etc
As usual I bought some factory ammo to compare my loads to and was disappointed with the accuracy with factory loads.
Amax was 2" @ 100yds, the SSTs were3".
Pulled the scope and replaced it with a Weaver 36x. That confirmed this rifle was not shooting factory loads well at all.
My loads were better but not great, I've tried preliminary loads with 140gr Berger, Sierra, Hornady SST and 120TSX and Hornady 129IL. 1 1/2"-2" is typical so far @100yds
The rifle was then parked while I moved and then hunted ...
I think the cartridge is fine but if I don't get a load that will shoot, I'll be ordering a barrel.
This is a sample of one and I'm not done yet. Wish I had a better report for you!
