I probably get a failure to fire maybe once every 2-300 rounds of .22 rimfire. You can take the cartridge out and rotate it a bit and it will fire the second strike almost every time.
I have a French Unique Model L which is one hundred percent in feeding and extracting and it is really accurate for a short barrel. It does misfire more than most, probably about once every couple of boxes.
I don’t recall a single time when a commercial centerfire round failed to ignite.
I have never had any real trouble with any brand of .22 rimfire except the Remington viper with the flat point. I have had that flat point catch on the feed ramp of several different guns. It seems to catch more on my Remington 582 than any other gun.
I even bought a few boxes of .22 mag made in the Philippines and it was fine ammo. It was also a little cheaper.
CDNN had Scorpion in 500 count bricks for $50 recently. Stuff shoots good, and it’s plated.
