I just picked up a new 10/22 and headed out to sight it in. I was shooting the brass plated Rem Golden Bullets. I've never used them before and I was amazed at how dirty these things burned. I went through about 150 rounds and could not believe how much residue built up on the magazine, let alone in the action. My fingertips were black by the time I was done. I did have one fail-to-eject and one fail-to-feed. This is the first .22 I've owned. Anyone have experience with this ammo? I'm wondering if most .22s burn this dirty or if it's just this type.
