yes - .35 Rem with 200gr. Scalloped Jacket RN.

We shoot a cannon with a sleeved 1-1/2" bore. We shoot 1.4" cast & patched WW balls from it, actually won the cannon shoot with it.

I cannot envision trying to stop that heavy cannon from rolling back when we fire it, let alone shooting something like that from the shoulder. Of course, the cannon weighs well over 500 pounds - and we don't cheap out on the powder.

I assume the 2"(50mm) ball is at least a 2 pounder or maybe 2 1/2 pounder, since a 1 pound is 1.67".
