[QUOTE="Willys46, post: 293049, member: 6536"] I know your frustration. You think you found the sweet sot, then BOOM! It goes to hell. I hate to say this, but it might not be a loading issue, it may be a gun issue. It says you’re shooting a 308. This is how I would approach it: 1. Buy some Federal Gold Match in 175’s or 168 and shoot some factory ammo. Most 308’s will shoot FGM as good as most hand loads. This would be to determine a base line. Shoot all 20 over the chronograph. The .25 moa groups might just be flukes. .25 MOA groups do not grow on trees. If I were to guess the 5r is a .7 to .85 MOA gun. 2. Then start loading form there. After you shoot your 3 shot groups and find the best group. Try loading some .1 and .2 over and under that load to fine tune. Are you shooting single feed or Mag length. Most 308 mag will only hold a 2.800 OAL. I would tune a powder charge instead of a seating depth. The 308 and SMK handle a jump just fine. What powder. Most find 43-45grs of Varget behind a 175 SMK seated at 2.800 to be satisfactory for a 308. Also check out snipershide.com in the reloading section. They have a great 308 load section. [/QUOTE]
