Looks like Norma has some interesting new 22LR ammo to try. It is similar to the 100% copper bullets CCI "makes" - I have never seen them on shelves anywhere or online. They advertise 24gr 1700 FPS but I am assuming that is out of a 16" barrel. Looks like it also has a flat profile which I have seen people comment works well on theirs. Mine did not really like the federal punch ammo, but my magazines are getting old and dirty from some really cheap blazer brass I bought that was covered in gritty residue. Might order some to give them a try.
