6mm Creedmoor comp contour barrel
I had pretty high expectations to begin with but this barrel is a tack driver. First load I put in it for break in shot under 1/2”. Sped up about 60fps in 150 rounds. Headspace was perfect, about + .004 from factory Hornady brass to fire formed. My load now is 41.0gr H4350 108 eldm Hornady brass Fed 210m 3080fps sd5 and .2-.3”. Couldn’t be happier. Was going to build a dasher but never got the barrel I ordered from somewhere else. Buying another one of these when they come back in stock.
