Good barrel for the money, but load sensitive.Review by
I was planning on using this for an "all around" build, hoping I could get good velocity and still be able to carry it around without paying too much of a weight penalty . I was expecting slightly tighter groups across the board but found that the barrel only liked 2 out of 6 bullets I tried working up loads with. 62gr Varmageddon HP was the best by far, with multiple loads around .25 moa. The other bullet is the 68gr Hornady BTHP, I found one accurate load at around .75moa. The SD/ES of this barrel aren't that great either, I have another Rainier barrel that has standard deviations and extreme spreads half of what this barrel has. These results were duplicated with handloads and blackhills ammo.

For the weight, accuracy and velocity, I'd just the same get a slightly longer barrel to get the velocity I want. Good barrel, just had my sights set too high I guess.

Super accurate with 69 grain match. Almost regret putting a strike eagle on it. Does sub moa all day long and even shoot cheap 55 grain well (Posted on 9/27/2016)

Fantastic barrel. First five rounds during break in got me a hard zero, the next five rounds were sub moa without even trying. Significantly better than the Odin Works barrel it replaced. (Posted on 9/14/2016)

Best mid-range barrel I have ownedReview by
I went through the barrel break in that was provided and oncd I developed a load for this barrel it is spot on every single shot. At 200 yards using HPBT 69grn I am achieving a 1.1"-1.9" grouping. Using Hornady and Nosler factory match ammo it can still achieve a 2" grouping. The longest shot I have taken so far is 603yds and still rang the steel every time 10/10 shots. (Posted on 8/26/2016)
