My freebore was short so oal may not help, but I was running alpha srp brass cci 450 varget and I was at 40.8 but in a 9 twist. Was getting good results for a bit then they just didn't want to shoot anymore. So I am going to burn up this barrel with 69 tmks and then I will throw on a 8 twist and try again.
Seen a couple other places that had the bullets yesterday. I think I will have 600 sitting for a bit till I get the 8 twist barrel on. Have 3k tmks rite now though.
