Rifle hunting bolts usaully last many 1000s rds.Use an old tooth brush,scratch around the fire pin and lugs will clean out any micro shit after every hunting trip or range use.Maybe if you fired 20-50 rds at the range,scratch with tooth brush as above,put a micro spot of oil in the little moving parts and rear bolt cam.Wipe down and put away.Years ago i had a old mossberg 308,put at least 4000yds thru it,most barnaul ammo on roos befor a bolt lug broke.
