Stove Pipe Jam
I have a Ruger 10/22 that has recently started to have a problem. Every 100 – 200 rounds I am getting a stove pipe jam (the extracted cartridge gets caught in the bolt as the rifle cycles trying to load the next round). It does not seem to be magazine related, and as I said, it happens every 100 – 200 rounds consistently over the last several range trips.
I was hoping that somebody here might be able to give me an idea as to what could cause this kind of jam. Recoil Spring going bad? Bad lot of ammo (so far all of the ammo this is happening with is from the same case)? Bad extractor (I looked at this and it “looks” ok, but I’m no expert)? Built up “gunk” in the chamber? Any ideas???
