Do the math for guns of equal weight and loads of equal velocity, and the difference in recoil won't be nearly as much.
Correct. I was contrasting the old timers with modern target shooting practice, including the fact that most of us (not all) use heavier guns these days at the traps.
The velocity of the 3 1/2 dram load of bulk smokeless was also assumed to be 1260, but Drew's chart indicates it may have been even faster than my modern version.
If both guns are 7 1/2 pounds, the load 1300 FPS (re Drew) and we use 49 Gr. bulk smokeless and 28 gr. WSF to accomplish this, the recoil energy is :
38.7 vs 30.6 for 26% increase in the bulk smokeless load.
I still think our trap shooting forefathers were a sturdy breed.
