[QUOTE="RegionRat, post: 1439621, member: 57231"] If the rig is brand new, I would also double check the twist rate to make sure it was not mislabeled by accident. It really sounds like it should group better. I might recommend you keep some BlackHills 77 OTM ammo handy. It can be used as a reference ammo to troubleshoot and debug. This rig should shoot 77 SMK just fine, but 80’s might not like that 1:8 twist. Most service rifles are migrated to 1:7 and use 77 SMK for the short lines and 80 SMK single fed for the 600 yard line. There are many other variations on this theme, but the majority of the rigs I see use something close to the above. The new rules allow scopes and as a result, I have seen my own White Oak upper groups as well as several friend’s rigs shot from the bench with BH ammo and we can easily shoot less than 1 MOA and even better with tuned hand loads with 10 shot groups. (The only problem this presents is making excuses later on... ). The point is, a service rifle is a fairly standardized item these days and bbls from the better shops are shooting very well with standard ammo in 77 grain. A bolt gun with a decent bbl should be able to shoot as well or better with tuned loads, or there is something wrong. Your >1MOA goal isn’t out of line and I am hoping you can find the issue. The NJ Highpopwer club web site has a tab called Reloading Stuph. You will see many SR loads on that site with several bullet weights and powders. [URL]http://www.radomski.us/njhp/cart_tech.htm[/URL] Your Varget powder as well as several other good ones are shown with good bullet combinations. Good Luck with the debug. [/QUOTE]
