I've yet to see a custom Ruger or BFR with trigger work that will compare to the FA trigger with an action job. The FA M83 trigger is closer to that of a nice bolt gun.
I have yet to feel an FA trigger that can compare to a properly tuned Ruger or BFR. You can't seem to mask that rubbery tightly wound spring feeling. I'm sorry, but Bowen, Huntington, Harton, etc. can tune a Ruger/BFR to the point that they really have no equals. The only thing smoother -- potentially -- is a Smith & Wesson.
