A Little FYI: I went to the range today and spent about 1.5hrs shooting the hell out of my 10/22. I tried 4 brands of ammunition. All fed without a problem, out of roughly 400 rounds, I did not experience one malfunction, not one. I used Remington 36grain HP High velocity , Federal Gold Medal, Remington Target, and German ammo called Dynamit Nobel---given to me by my father in law this was low velocity ammunition generally used in his 22 revolver. All of the ammunition was fairly accurate as I was shooting at 50yards and holding a real tight group, so much that I actually punched a hole in the cardboard. As for clips, I was using my stock 10rounder and a 25 round plastic feed lip butler creek. To my surprise, and I was trying, there was no jamming. Although, all the ammo worked pretty well, I am going to stick with the Remington 36gr HP high velocity. They had more punch. At one point I just kept pulling the trigger and ripping through my 25 rounds in about 5 seconds. I am highly impresssed with this rifle, so much that I did not even get around to shooting my Bushmaster.
