I have a Ruger K77/22-VHZ. It wasn't too accurate out of the box. Sent it away to a fellow who stiffened the bolt, redid the chamber to minimum demensions, and redid the crown. I redid the trigger. Now it is a tack driver. Hogdon Lil-gun, works really well in the Hornet. High velocity with low pressure. Not sure how they make it do that, but it is good stuff. I shoot the 45gr. Speer soft point. Wacks ground hogs really hard. Low noise is good for built up areas.
