It had been a while since I shot a 22 LR. I bought a 10/22 for plinking - I had a mis-fire and so I looked at where the firing pin was striking the case. It very close to the edge of the rim. So never thinking about it before and in thinking that "rim fire" probably means close to edge of the rim? Is where the firing pin is striking correct or should it be closer to the center. Becasue Based on the firing pin configuration there is not alot to adjust.
