So the second time I went to the range I shot one group with the brake and the other 3 without it & there was no real difference in accuracy just poi. I have it soaking overnight with some wipeout. It was heavily streaked with copper when I got home despite being squeaky clean when I went out this morning, I know some will form but this seemed excessive. I'm going to shoot it tomorrow from a rest & see if removing the bipod changes things. I'm obviously going to try and find other ammo and eventually load for it just snowballing ideas right now
