I'd love to love the Ruger 10/22, but I hate mine.
I bought it about 10 years ago, and have probably less than 200 rounds through it.
Can't get it to feed or extract over 50% of the time. Swapped in a Volquartsen extractor and it made about a 5% improvement. I've tried about 8 different types of ammo, makes no difference.
It just hangs on the wall, collecting dust.
Oh well, my Marlins seem to work just fine.
That sucks. When I first bought mine I had a similar problem. I also have had a feed problem with EVERY Ruger magazine.
For the magazine problem, I had to disassemble each magazine, clean, reassemble and rewind the spring. Fixed that issue. I don't know why it fixed it. I don't know why all the actual Ruger 10 rounds mags had the problem in the first place.
For the first problem I just really soaked the action in Hoppes and let it sit up side down so the Hoppes could work on it. Then wiped it off and put a very, very light coat of remoil on it and wiped that off and reassembled. Haven't had a hiccup since.
Only thing I could figure was factory oil had sat in it and stiffened.
As far as cleaning from the muzzle end, I have .22 bolt action Cooey repeater 60 that has been in the family since before I was born and it has never been cleaned from anywhere except muzzle end and still shoots straight. Same with the Winchester 74 semi auto made in 1939.
