The Ruger 77/22 was the first higher priced .22 rifle I purchased over 20 years ago. I spent a lot of range time, tinkering and money on every conceivable brand of ammo trying to get it to group instead of pattern. Never did get under an inch a fifty yards, with most groups being closer to two inches , so I sold it. Had the same issue with a Remington 541T HB and it cost even more. Rifles are like people, they all have their individual quirks.
