gatsby- I realize Fosebery's concept of the slug - but I'd personally much rather have a hardened round ball of 12 bore size travelling at 1,500fps, than a slug weighing 150gr. to 200gr. more at 900fps to 1,100fps - any day. The round ball will exit an Indian Elephant's head, while giving a point blank range of about 110 yards. (PB= no more than 2" above or below line of sight) Now, the slow moving slug does have some advantage over a round ball if make into one of Forsyth's 'shell's.

The use of a patched round ball was mentioned as an experiment as out of a 'bore' gun, within reasonable hunting ranges, it is superior in trajectory and provides adequate penetrtion. Hitting the right spot is of paramount importance.
