.....getting worse. Having a SIG 522, S&W M&P 15-22 and several other 22 semi auto guns I do a lot of 22 shooting. Due to the volume of shooting, I have to mostly use the inexpensive Wal Mart Federal and Remington 550 bulk packs. Now I know you shouldn't expect the same quality from the cheap stuff as the high price spread but the Remington is getting ridiculous. Duds are fairly common with Federal and Remington 22LR, mostly Remington, but yesterday was exceptionally bad. I ran about 30 rounds of Remington through a Browning Buckmark, along with 20-30 rounds of Federal. No problem with the Federal. Three duds with the Remington. The Remington also jams feeding in the Buckmark. Then I ran two mags (48 rounds) through the S&W M&P. Ten duds but two rounds fired on the second try when the case was turned and shot again. For some time now when I get a dud I try to fire the shell again after turning it so the firing pin hits a different spot. Maybe one out of 15-20 rounds will fire. This demonstrates that there was at least some primer in the rim. I also pull the bullets and look for primer in the base/rim of the case. Always there is none. Thus showing the poor quality control during manufacture. I put the dud brass in a pill bottle. Yesterday I noticed I have to get a bigger bottle. Years ago a 22 misfire was almost unheard of. If it happened at all it was from a light firing pin strike. I would just stop buying Remington but a couple of my guns feed and shoot it much better than Federal.
