My Ruger 10/22 when from 1.5" at 25 yards to maybe .15" at 25 yards with just using a 16" fluted green mountain barrel.

I say maybe .15" because I've never measured but is just bigger than a ragged hole.

At 10 feet it shoots through the same hole over and over again. First time out was a shocker.

The only other mod I have is a trigger job that cost me $40. It was there even before I upgraded the barrel so it had no real effect on accuracy.

Main Shooter, those are some real nice rigs. Mine is fancy but not that fancy.
