[QUOTE="Baylor243, post: 2000751, member: 114468"] I have a browning A-bolt 300 win mag and it shoots 5/8” or better groups (5 shots) with cheap-o Winchester factory power point 180’s....and it’s nowhere near the mfg recommended BOSS setting. I shoot it set at 9.6...factory BOSS setting chart says 0.5. Who knows why? Who cares? Not me. It shoots great. I’ve filled the freezer quite a few times with those cheap rounds and I’ve never found a hand load that will out shoot it. I quit trying, bought a case of ammo and never looked back. Yes, I’ve had several bullets separate but it dang sure packs a whoopin on whatever I ask I also had a 243 M1000 Eclipse A-bolt that shot lights out when set dead up on the factory settings. I shot the barrel out of it and gave it to my brother in law. He can’t shoot for beans anyways. Long story short, sometimes ithe BOSS just doesn’t make sense with the factory charts. Good luck.
