Re: Tunney or Jewell
Dirt and dust can be a problem for any trigger or other rifle component for that matter. Best policy? Keep yer crap clean. I hunt moose, sheep, bears, deer, elk, goats, caribou etc.....from Mexico to Alaska (including Kodiak Island) with two different rifles. Both have Jewell triggers set to 7oz. Have not had any trouble yet. That said, if set improperly, they can fire at odd times. Then again, brakes on vehicles that are not set properly can cause accidents as well. Bottom line? Set them right and keep them clean.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
