I've bought 3 different 10/22's. They were all used and never had an issue with feeding and firing. My carbine shoots everything just fine, even 1080fps. I always use high velocity round nose ammunition, doesn't matter the brand on the other two. I have a fourth one (50th anni) new in a box, I'm scared to try it out, with how many people I hear having issues with recent 10/22's.
