[QUOTE="Willys46, post: 188142, member: 6536"] [b]Chrono?[/b] What Chrono are you using and was the light conditions changing while shooting. Mine will read different if the sun goes behind a cloud. Also, is there a load that is in the 90-95% densit (powder volume in Case). I have had better SD with full loads of powder. More uniform burn. I might be wrong, but the gun is going to have little to do with velocity spreads...BUt the group will suffer if not bedded correctly. One other thing i have read is using non magnum primers..I have not tried it in my 7 rem mag, but it was suggested to tighten groups up. Willys [/QUOTE]
