I have had my Walther P22 now for close to a year and have 1,000's and 1,000's of rounds through it. At first, it would fail to feed every so often, although CCI Mini-Mags were it's preferred diet. Rem Golden Bulets were just okay. it doesn't like Winchester Hi velocity at all! I ran a whole brick of Federal bulk pack (550) through it a week ago and then a mini-brick (325) of Federal auto match on Sunday and had ZERO problems. That's over 800 consecutive rounds in a P22 .22 LR pistol without any FTF, FTE, or anything. Just went bang every time I pulled the trigger. This P22 gobbles that cheap Federal ammo up like my dog does jerky treats now. It is not as accurate as my Buckmark, I know that, but dang, it sure is a fun little pistol to take out to pop dirt clods and shoot those little rimfire spinning targets with! It's more accurate for me than a lot of posts lead one to believe; maybe I just got a good one, but whatever, it's wore in (broke in?) just right now and is at the top of my list as one of the most fun pistols for some plain old plinking! I like it! Once you learn the trick to reassembly, it's a 10 second job too.
