I had the same problem with "bipod jump" with my rifle until I got a Holland muzzle brake installed. My gun likes 168 gr Sierra HPBT and loves 110 gr Sierra FB HP. Picture of my rifle and a group I recently shot with 110 gr Sierra over 46.0 gr Varget with Lapua brass and Fed 210M primers. Measures .420" CTC including cold bore shot and thats 5 shots by the way. The combination of light bullet and the muzzle brake allow me to shoot with almost no felt recoil. That has upped my confidence and really helps with flinching. Overall, in 300 rounds I have shot, I would call it .75 to 1 moa with factory ammo, .5ish with handloads, and has the ability to shoot in the .2's and .3's with perfect conditions, 5 shot groups. I know at least a few people who have shot in the .1's (*cough* z71rat *cough*) with 3 shot groups and factory ammo.
