Recoil speed x trigger pull weight
|
I have both a .470 and a 9.3x74R DRs.
Because the rifle is much lighter, the speed of the kick on the 9.3mm is much greater.
The 9.3mm truly "kicks" while the .470 only "pushes" (although farther).
The question is: which one would you set up your TRIGGER PULL WEIGHT heavier??? The 9.3 or the 470?? Which one is more likely to double charge the faster kick of the 9.3mm or the lengthier push of the .470???
My original idea was to set up the .470 a pound heavier, but could it be best to do the opposite???
Would you consider 3.5 lbs as to light for a .470???
Thanks

IMO 3.5lbs is pretty light for a big double.
Personally I like 4-5 pounds for both front and rear triggers on a 470NE double.
Thesedays a lot of the 'new to doubles' guys want their DR trigger pulls really light, some times 3 pounds or lighter.
At that weight it is no surprise that some are having occasional double discharges as well as accidental discharges.
If the two doubles were mine, I'd prefer them both to have similar pulls of between 4 to 5 pounds.

All my rifles go off at 4 pounds. That really simplifies taking the shot and it becomes subconscious when hunting. You and the rifle trigger are one - when it is time to fire, the rifle does and the game falls.

And of course pull weight is only part of the deal.
Sear depth of engagement and angles are just as important in producing crisp yet safe trigger pulls.

thanks for inputs and I agree angle is so important for avoiding unsafe triggers
But my question remains: do you agree that, if inertia is opposite to acceleration, a lighter rifle should be "unsafer" at same angle and sear depth???

My experience is that rifle weight should be proportional to trigger pull. The heavier the rifle (shotgun) so should be its trigger pull. The worst scenario is a big calibre/light rifle with a heavy trigger pull, IMO.

My Jeffery before the triggers were fixed went off at 11 lbs and 13 lbs. One wondered why I couldn't shoot 'groups' well with it at those weights. I used to break into a sweat trying to squeeze the trigger especially the rear one. Used to double as well. But the gunsmith fixed that, except when I muck up now.

I once read; the rear trigger should have heavier pull.
Typically it will be operated with the stronger part of finger... and will therefore feel the same?
Usually 1/2 pound difference if u r in the 4 or 5 pound region i read.
So that's how i set shotguns up now...
As for trigger pulls on a heavy dangerous game rifle which gets used on dangerous game by very scared untrained newbies... 11 and 13 sounds perfect?
Just my $.2
