22lr overload?

So I was at the range last week shooting my new 10/22. I was using CCI Standard Velocity. I had a ftf. I ejected the round and it looked like the firing pin hit it pretty good. I rotated it 180 degrees and rechambered it. Went bang but landed about 1 inch low and one inch right of my existing group. It also smoked like crazy. Anybody else had a bad .22?

This happened to me once before with one of my other 10/22s and it blew the extractor off.

Yes, it is not uncommon for priming compound to not be equally distributed in the rim and, sometimes it just doesn't make it to part of the rim. That's why you has a misfire. As far as the smoke goes, did you inspect the case afterwards? You could have had a ruptured case. I've had the same thing happen with Eley .22lr. So, it happens with high end ammo too.

The smoke was from an incomplete powder burn, likely caused by the poor ignition.
That's why the bullet hit low, it was going slower than usual so you had more bullet drop.

Actually...

What may have happened is that the first primer strike weakened the rim, so that when you re-shot it, you got a minor case head separation. That creates smoke and may reduce chamber pressure, in addition to being potentially (but rarely in a .22LR) dangerous. I hope you had good eye protection!

For this reason I don't recommend re-shooting struck .22's. Most of the time nothing bad happens, but it's not worth the risk of damaging your rifle or getting bits of brass shot into your face.

The only consistently bad 22lr I have seen is Remington GB. Probably about a 5% defect rate. And for the five or six cents that a 22lr round costs, I wouldn't re-chamber a round either.

Thanks for the good answers guys.
