GunAddict, I think your bolt guns would benefit from full length sized cases That's been proved by top level competitors using shoulder fired rifles since the 1950's in most disciplines and the benchresters pretty much all moved away from neck sizing to full length sizing a few years ago.
Most folks who neck size think cases so sized fit the chamber better and align the bullet more concentric to the bore. They don't; especially when they've been fired a few times.
