I never had a double rifle but several scatter guns. learned to keep two fingers off the double trigger the 10 ga had LOL.

I have a Corbin swage press and .459 dies plus around 3000 jackets left I used for swaging bullets for the 95 Marlin and later on I swaged some for the .45-120/3-1/4 pedersoli 74 Sharps and loaded them with 118 gr of 1F Goes using the 350 to 500 gr swaged jacketed bullets in that rifle and they shot very well better accuracy then I could get from the O-3-A3.
I was always fascinated with the doubles but never got a rifle.
