Christensen Arms MPR 300WM - New Barrel Decision

[JohnnyThe]

Hi,

This is my first post..

I bought a CA MPR 300WM and like the rest of us, my experience has not been pleasant. I really want to love this rifle and had sent it back twice, now there is nothing left to discuss with CA. On my last go-around the barrel shot less than MOA (0.90) in a best of (4) scenario with 215gr Berger Hybrids...

I am looking to re-barrel this rifle with a carbon PROOF solution..

I am an avid shooter for many years and own a number of precision rifles - Precision is what I am seeking. I live in NJ and have access to shoot out to 1k locally but most of my target time is at 300yds. Once a year I make a pilgrimage deep into PA where I have access to 1760yds. I have heavily invested in Black Hills 190gr Match HP factory loaded and Barnes VOR-TX 180gr TTSX BT factory load.

Since I live in NJ, the gun will not see a suppressor so I have decided on a length of 26"

The question - 1:9 / 1:9.4 / 1:10 Deciding between these is where I'm struggling.

Please let me know your thoughts - Also posted in ELR Forum

Thanks!
John

I run a Bartlein 1:9 for my 300 prc and shoot 220 Berger Hybrids and they shoot lights out!

Thanks Mike. What twist would you use if limited to 180/190gr?

If 190 was the max I was going to run I'd do a 1:10.
