Fellow Firearm Enthusiasts,
Except for my one and only repeater, a Prohibition Era Model-12 Winchester pump, all my shotguns are SxS with 2 triggers and semi-pistol grip.
After a bit of very careful dowel and sand paper work inside the right barrel only muzzle, most of those are now choked —> Right Barrel True Cylinder (aka: no choke at all) and —> Left Barrel Full Choke.
For larger than dove and quail upland bird hunting, I prefer to carry my doubles with #6, or #7&1/2 lead shot in my right no choke barrel.
And, #4 high velocity lead shot in my left full choke barrel.
Back during the early to mid 1970’s, I have even carried one such double 12 bore in the Feather River drainage (Northern California) during overlapping deer season and pheasant season.
Loaded with a rifled slug in the right barrel and high velocity #4 lead shot in the left barrel, I was ready for whatever I might encounter, within the thick foliage.
I never did get a shot at a deer with that setup but it was not for lack of walking quietly and hoping.
With all that, my answer to the “Which Trigger” question is: I go for the trigger / barrel that is loaded with the type cartridge best suited to whatever I am suddenly encountering.
In other words, I have no preference for the sake of tradition or whatever else anyone can think of, except a split second decision according to what type of critter and which specific charge is best to bag it with.
As for double rifles, I have owned several, all with semi pistol grip and two triggers.
Apparently, I am so dim witted that I have not noticed any of my doubles, neither any of my friend’s double rifles preferring any particular sequence in firing one barrel or the other first, as it pertains to their regulating shot for shot from standing with sticks, punching holes in paper targets.
Aside from the occasionally encountered front set trigger (a totally useless feature IMO), on a very few double rifles, never have I otherwise noticed the front trigger pull weight being lighter than the rear trigger pull weight on any of mine or any of my friend’s double rifles.
This to include having fired all of Cal Pappas’s (RIP) remarkable collection of English double rifles.
Initially, from reading about the golden years of British Hunting Safaris to Africa and India, I was convinced that I should always fire the right side barrel (front trigger) before the left side barrel (rear trigger).
However, back when Cal was still alive and while PH, Gary Hopkins was visiting Alaska, we went to the rifle range for a bit of casual shooting.
Twice I saw Hopkins experience a double discharge from a box lock SxS rifle in caliber .450 No2 NE.
He said it was from pressing the front trigger first, resulting in accidentally strumming the triggers during recoil.
From that day onward, I abandoned the romance and tradition of firing the right barrel first, with hard kicking double rifles.
I always select the rear trigger first on serious kickers and that is that.
I do not recall any more if Mr. Hopkins switched to selecting the rear trigger first or not.
At that time he did not own a double rifle anyway.
Also, before anyone presumes the recoil of that rifle was too much for him, he was well over 6 feet tall, young and “all meat, no potatoes” so to speak.
That same day, I watched him fire a 3 shot string from a custom built Brno 602 Magnum, caliber .460 Weatherby, (Weatherby factory loaded ammunition) as fast as he could run the bolt and all 3 shots were clustered into a fist size group together on the paper target @ 50 Meters.
Therefore, I suspect that strumming the triggers might happen to anyone, especially if they shoot hard kicking doubles quite often.
At this stage in my life, it cannot happen to me because I always choose the rear trigger first when messing around with seriously hard kicking doubles.
The one and only buffalo that I’ve taken so far, was with my own at the time, caliber .450 No2 NE double rifle.
And you guessed it, I fired the left barrel (rear trigger) first and then the right.
It was very satisfying to see him drop both times that I fired (left and right / soft and solid).
Although I had hastily then reloaded with two solids, I didn’t need a 3rd shot.
He was thoroughly expired by the time we walked the short distance up to him.
Cheers,
Velo Dog.
