Probably not too bad. 2000 gr cast lead bullet, some powder and primer.OMG What a CANNON!!! Wonder what that thing costs per shot?!?!
I've humped a 32 pound M240B with ammo, so the term "light enough to carry" is relative to the poor bastard that has to carry it.OK Carcrash, you are the OP on this. Clarify your meaning of "light enough to carry". Do you mean portable at all or light enough to be truly useable as in target shooting or hunting and carrying all day?
