Create a channel Learn moreAnything special on the rifle other than the boltface and barrel?I built an AR 10 in 338 RCM. I use 6.5 PRC brass necked up.
Its 18" light fluted barrel weighs 7 lbs ll oz. Without scope.
Wanted something different, It makes a nice handling hunting cartridge with heavy bullets larger game.
Its accurate with 160 gr Barnes to 250 gr hunting bullets at 2575 with RL 26.
300 WSMSpecs on this build?
Thanks

I'm building one in 6.5 PRC as a range gun, it will be another month or so before it's complete.
It's a 5oz buffer. I have a 9oz I'm going to try when I get out and shoot either today or tomorrow. The one load I quickly put together was 2840fps, 190 berger vld, 61.5gr of H4350. This load was a bit hot, and the recoil was more than I'd like. I currently have several loads put together with 180 berger elite and various weights of H4350, we'll see which is the most accurate and go from there.5 oz buffer?
What are your velocities with the different loads?
Thanks
Nope, you can buy the KAK magnum bolt, or complete bolt carrier, and upper reciever, together for the easy button.Anything special on the rifle other than the boltface and barrel?
I have been considering this setup in the back of my mind.
I figured it was on the low end since it was one of my starting loads, my manual says 47,600 psi with 58gr of IMR4350, Hodgdon says 54,900 psi with 59gr of H4350.Quickloads says your load is at ~ 47,100 psi
Max for the 300 WSM is ~ 63,800 psi
Your load is very low pressure
54,900 psi, with a 180 grn bullet?I figured it was on the low end since it was one of my starting loads, my manual says 47,600 psi with 58gr of IMR4350, Hodgdon says 54,900 psi with 59gr of H4350.
This is for hunting, I wanted to be shooting at least 1" at 100 yards and the bullet going at or over 2750 fps with whatever was the most accurate. I'll probably play around with my 62gr load in the future and see what kind of groups I can get with that. That load was going about 2900 fps.
