You've gotten the technical answer ....

but make it easy - equate 2 3/4 Dram to about 1150 fps
and equate 3 Dram to about 1200 fps

So a 3 Dram shell is faster than a 2 3/4 Dram shell.

( put the velocity, weight of shot, weight of gun in the recoil formula that OneOunce and I both gave you yesterday - and weight of wad ) and calcuate the recoil...
