As stated above, no feeding issues or failures all day. The federal bulk I bought had some weird corrosion-looking gunk on it that Hoser says is wax, but based on how much of it rubbed off when I tried loading up a mag, I didn't want to foul up my new gun and mags. It was literally collecting on the feed lips of my mag after only loading about 5 rounds, so I just left it at home.
What is disappointing with the M-22? It was shooting about a 4 inch group at 100yrds and I wasn't exactly shooting from sandbags or anything...
