[QUOTE="Bart B, post: 106480, member: 5302"] [b]Re: where is your \"sweet spot\" for bullet seating/30 cal[/b] Across twelve .308 Win. barrels, four .30-.338 Win. Mag barrels and a .30-06 clunker barrel, best accuracy was with the bullet seated into the lands. Especially if bullet runout in loaded rounds is a bit much. However, if bullet runout on loaded rounds is very, very good (no more than .001-inch with the dial indicator .600-inch in front of the case mouth where the bullet's rested), they can jump around 2/10ths of an inch and accuracy is great. That's because the firing pin drives a rimless bottleneck case all the way forward such that its shoulder centers in the chamber shoulder so the bullet gets a straight start into the rifling. Some folks get 1/2 MOA accuracy at 600 yards with very straight loaded rounds shooting the bullet almost 1/4th inch into the rifling. [/QUOTE]
