I finally had the opportunity to try some of the 50gr zmax. I have a Winchester stealth model 70 heavy barrel custom. 1:14. 22-250. I was shooting them over varget just off of max load. They were literally keyholing at 50 yards. So to head off the barrel being shot out.... It will still shoot hornady match 52gr bthp in the same hole same with. 55gr v max. Right now I'm shooting 36 gr Barnes out of it for chucks. Same... The Rifle likes. 2.380. I tried. 2.340 to
2.40.
