Getting back to the original topic (12 pages ago), I don't really think there is as much of a problem as perceived. One type of factory ammo won't chamber, and the Vmax that are loaded past max OAL won't chamber.
For a non-custom rifle, the chamber should be within SAAMI specs. Being out of spec means it wasn't cut right. If the chamber's not cut right, I'd be wondering what else wasn't done right. Once he starts shooting it, it's his problem to deal with, not the dealer's.
