4,300fpe with a black powder rifle - well done! Bet Forsyth's 'shell's would be kinda special!

8 bore, I think.

"No.1 was charging: shell hit him in the mouth, exploded in this throat, and blew his head into pieces."

"Nos.2 and 3 were both hit far back in the body, and low down: in neither instance would a common ball have had the least effect. No. 2 ran150yards and fell, and No. 3 stayed where he was. On opening, the whole cavity of the body was full of extravasated (sic) blood."

"No. 4 I must day would have had little chance of doing mischief, whatever sort of projectile he had met with, for the shell struck ihim full in the forehead, making a clean round hole on entering, but blowing the back of the head and bones of the neck into little bits.
In addition to these four, I finished with a shell another tiger which had previously received three common balls, and had still some life left. The effect was equally instantaneous."
