My rifle rifle just crossed the 1K shot mark. Is there anything special or any regularly scheduled maintenance that should be looked into at this point? It is currently shooting well under 1/2" consistently, and the smallest groups are the ones I have gotten here lately since I have pushed the bullet out some. Rifle is a turk mauser action, Shaw heavy sporter barrel, 30-06 min saami chamber. Who knows how many rounds that receiver really has through it... Thanks for your help.
