I recently put a spring kit in my 10/22 that reduced the trigger pull down to about 3 lbs. I went out to the range and it worked great. About a week later i went out again with the same ammo(Remington Thunderbolts), and about every third or fourth shot wouldn't fire. Looking at the casings, none of them seemed to be indented that much. Should I put my stock springs back in, or is there something I am missing. I really like my reduced pull and would like to keep it if all possible. Thanks for any suggestions.
