winchester .22 69A bolt action problems

I had a couple problems with my rifle, first of all it had a hair pin trigger and secondly sometimes when i relaod it, it fires without pulling the trigger. I adjusted the trigger to the sear . It doesnt have the hairpin trigger anymore, but while i dry fired it a couple times it fired without pulling the trigger. Can anyone help me out. thanks

thanks for the info. I absolutely love this winchester it was my dads and he got it in 1961
