[QUOTE="CNY Yote Hunter, post: 3011253, member: 109650"] Late to the conversation but I agree with others on the powder. H380 has been the best powder for the 22-250 I have ever used. 38.0 grains and a 55 grain projectile has produced some of the best groups I have ever shot with mine. Hence H380- 38.0… pretty neat lol. I would take the .020 off the lands and forget about that honestly. I’m not sure how you measured your distance to the lands but I have found with most factory rifles, getting to .020 off the lands has the projectile **** near not in the case at all. The manufacturer almost always leaves more room to the rifling cause you never know what someone has bought for ammo and weights that they want to shoot. That being said, do some reading on twist rates, find a projectile that falls right in the middle of the lower side and higher side of your twist rate and start there. The Nosler reloading manual has been one of the best for me, they list the most accurate load tried and highlight it. Honestly I have started with those for quite a few rifles and have been extremely pleased with the outcome. Most other books do not show you the most accurate powder tested I have found although the more you get into loading the more of them you will want for other options at times. The .020 off the lands comment I made, the reason I wouldn’t worry too much about that is I have rifles like Rem 700’s that love the projectile that close to the lands and others that won’t group 3” at that seating depth. The Ruger American I have is one of those rifles that doesn’t like the projectile that close. If you are measuring your cbto, buy some factory loads and start checking what they are loaded to. I think you will be mind blown when you see just how much difference there can be with seating depths. That being said I feel through my time behind the gun that seating depth is far more important than powder charge.
