Thread: Hammer Spring 10/22 or Brno 581

As to the wear on the chamber, not that I can see. Someone has also said that it might me the shape of the pin. But then I hear from some that it should be squared off but others say it should be rounded!!! The misfires have been less since a massive clean out of the trigger group and a re-oil with a dry lube but we are lucky to get a five round group with out a miss. Have tried subs and supers in a variety of brands and it does not seem tied to one brand or the other. I think I will continue to seek out a 10/22 spring to see if that helps, as it is a non-destructive change. Thanks for the link to the 10/22 page.
