Last weekend I picked up a stainless Ruger 10/22 carbine to use for plinking and teaching our kids the fundamentals of firearms safety and use. I've shot several 10/22 rifles in the past and always found them to be very reliable.
Unfortunately the rifle that I purchased is jamming very often. It has less than 500 rounds put through it to date, all of which has been Federal Americal Eagle 38gr JHP bulk box ammo bought at Wal-Mart.
The problem seems to be failure to fully eject. Spent casings are stove-piping and appear to be severely bent by the extractor, and the subsequent round is being jammed in beneath and behind.
I've noticed that some of the unfired rounds have bullets that are pressed loosely into the casing. Loose enough that you can twist the bullets around inside the casing, but not so loose that you can pull it out of the casing by hand.
That said, I'm fully open to the idea that the ammo we're using is just crap and that it's causing the problem. I just haven't had a chance to buy some traditional ball ammo and try that in the rifle. I'm also open to the idea that the rifle is still within the "break in" period and this problem may go away after a couple hundred more rounds.
Thoughts?
