This is with a particularly good lot of CBC MK262 that will honestly sling .5moa groups through my bolt rifle with ease.
I just looked at the pictures on a bigger screen. That gun shoots bad either way. Something is wrong with it, the brake just makes it worse.
Do you reload? Some barrels are REALLY picky. Like BAD attention whore picky. Some combinations you'd not think to be problematic just are awful but then when you change up the bullet or powder it's like you went from Rosie O'Donnell to Claudia Schiffer. Run some 75gr & 68gr Hornady BTHP and ELD, 77gr & 69gr Nosler CC and RDF, Berger, Lapua Scenar, etc. w/ 8208 XBR, CFE223, AR Comp, with each. It may very well surprise you which one it likes--if the answer was always the same one for everyone, the others would sell zero, right?
