I have the savage 110 switchback in 6arc with bottom bolt release. The stock trigger would only adjust down to around 3.5 lbs. I replaced the trigger spring with one from a 12fv top bolt release, which broke around 1lb. The 110 now breaks at about 2lb. Both of my other top bolt release rifles trigger break around 1- 1.5 lb as well. Is there anything else that can be done without replacing the trigger to get the trigger weight down?
