[QUOTE="Lefty7mmstw, post: 1018519, member: 48043"] .001 really isn't undersized much. We are seeing just about that with many 7mm bullets too. As posted earlier make sure you have a bit of neck tension and go for it. The bullet will obdurate to fill the bore. Remember your groove diameter is really .300 and your bore is .308 so the bullet is filling 7/8 of the rifling part of the bore [I]before[/I] it slugs up. Even without obduration, the bullet has to displace the material moved by the lands. Either the bullet gets fractionally longer, or the material will fill in the grooves where it can; most likely both. [/QUOTE]
