Does the bolt close on the GO Gauge?
SAMMI spec on most chambers has about a .004" difference between GO and NO-GO so your loaded factory ammo is probably on the smaller sized end of its tolerances but should still be within range. Most ammo is made from the factory to be on the smaller (or loose when in the chamber) side of things. This increases the likelihood that a given cartridge will fit a variety of chambers with increased reliability in all rifles.
