I got a good friend of mine that owns a new 15-22, and his brother has a new ruger 10-22. They both shoot about the same at 50yds, we have often tried shooting .50cent coins at 50 yards with each of them. Even with a good solid rest, and real good ammo, you can shoot all around that .50cent coin for a while, just barely missing it by mere fractions. Then eventually you can hit it, but then rarely find it. "That's dangerous by the way" dont recomend it, since we only found two of 10, have no idea where the other 8 went. Another friend of mine has a 1980's vintige Ruger 10-22, that we shoot scoped at 100yds all day long. That older 10-22 seems to shoot better than the new model and I don't know why exactly. I know the guy that has the older one never cleans it. He has many thousands of rounds down range to boot. Also, about that 15-22 not having a forward assist, probably not a good idea with a rimfire don't you think. Talk about a slam fire, ouch. But we all like the 15-22 at the range, only have occasional hick-ups like the other person said, if you get in a hurry loading your magazines. But compared to the other older Ruger 10-22, which often don't go bang, misfeeds and jams, but clears quickly for another shot. You can trick out either rifle, many different ways too, lots of parts and dress up kits to hot rod em' around. As far as bump firing, "I like to be in another state & county" when folks are doing that, especially for the first timers. I seen a guy at a public range, standing behind the shooters table/bench try that 1 time too many! ( AK-47 ) He shot the top of that tables to peices, dropped 15 or so rounds right in the dirt not 10 feet out in front of him, and got "Banned & Barred" from that place for life. Lucky he didn't kill someone. I am sure he didn't do it on purpose, but... he still did it. I for one am glad he wont be back. I am sure that was an "isolated incedent" but WOW! what a dummy.
