Last week I picked up a new 10/22, that was customized by the shop I bought it from Acme Sports. I took some CCI mini-mags, Remington Yellow Jackets, and some Remington bulk. It came with a Butler Creek 25 round mag, and my Dad gave me two factory 10 round mags from when he used to have a 10/22. Everything went smooth at first, except it did not like the Yellow Jackets. Then toward the end with the last two mags loaded with the mini-mags I had problems. I would chamber a round, it would fire and eject the casing. The bolt would go all the way into battery, but the next round would not fire. All the ammo was from the same box. So I'm going to strip her down, and make sure everything looks good and give her a good lube. Also I'm not real fond of the scope that's on it. It's a Fire-Fly which I can find no info on them. Also the brightness settings only go to 7, and with the sun to my back it was hard to see the dot. So I may replace it with a Bushnell with multiple reticles to choose from, or another type of scope. I'm going to try and get it back to the range this weekend. May get a new scope tomorrow.
