Impact Action= Great
Bartlein Barrel=Good stuff
Trigger Tech= Good stuff
MPA Chassis= Good stuff
The only things I wouldn't do are the scope or the barrel length, but out purposes are different, so there is that.
I have three 300 PRC's and was a VERY early adopter. Pre production ammunition early. I have 1 in a 24" carbon, 26" carbon and 26" Bartlein stainless. All shoot better than me. I use different brands of brass in each to keep them separated. I run nearly identical loads in all 3, chambers all magically ended up identical...which...hallelujah for that. I run the 245 EOL and N570 in both carbons and will say this.
Whatever you choose to do with rifle parts....choose the best components. So far ADG brass is the winner in my eyes/experience. The lapua brass started out as berger factory 245 ammo and on the first firing was chamber size and had ejector marks. I tried some other Lapua brass and a middle of the road load...same thing. It just seems like the case heads are too soft. The ADG on the other hand....be careful because I think it lies when you're looking for pressure, case heads may be too tough. Either way, I hot rod that ADG and am on 8 firings without signs of failure.
When I go to a 22" barrel I will be looking to get more ADG.
