Re: front or rear trigger

With the greatest of respect. I believe that the difference in felt pull weight between front and rear triggers, has far more to do with the angle of force and the distence from the pivot to the moment of force (the finger) than differing sear release pressures.
With the rear trigger on a double trigger gun the trigger finger has to move the trigger in a more upward fashion at the same time as to the rear. The front trigger pivots more naturally around the pin. The front trigger is generaly also longer reducing the pressure needed to trip the sear.

The pull weights are actually cut with the front trigger lighter than the back. This is measurable with a trigger pull scale! The recoil of one barrel going off is what sets off the second barrel in a double that is prone to mechanical doubleing, and the fix is to build up the sear surfaces and re-cut the offending trigger. If a double is habitually doubleing when the first shot is taken, if you reverse the trigger pull the rifle will not usually double.
The trigger pulls are set differently for two reasons! #1 is because when fireing the right barrel, with a less than perfect hold on the rifle by the trigger hand, the finger will sometimes hit the back trigger setting it off as well, #2 because the recoil from the right barrel going off may disengage the sear on the left lock, if it is cut too lightly. These two reasons are the same reasons the right trigger is always the trigger that is fitted with a set trigger, if the rifle has one!
If your rifle works fine pulling the back trigger first, then do so! However because it does doesn't change the fact that the rifle was designed to be fired 1, Right, 2, Left, on a right hand rifle, and is set opposite on a left hand rifle.
