Re: Frequency of Sighting and cleaning hunting rifle?
Depends on the barrel, to some extent. I had a factory Ruger 7 mag action that had been bedded into a heavy, ugly, aftermarket synthetic stock, back when they really were fiberglass. One fouler, and it would shoot the next dozen in the .4's. At shot 13 the groups would open up to 1" or so. Great for big game, not great for the prairie dogs I was shooting with that rifle.
I am currently shooting 3 different rifles in 3 different calibers, with 3 different custom barrels. I have not yet hit a point where they stopped shooting. They are all sub-moa barrels... and I clean them regularly, usually after a day in the field, which could be anywhere from 20 to 100 shots.
