I will be spending a fair bit of time in Botswana in the next couple of years,so it is interesting to read everyones comments on the subject.

Correct me if I'm wrong but shooting a leopard at very close range with a heavy calibre would do nothing except pass right through the animal without expanding and unless you hit a vital area, you would have a problem.

As far as penetration is concerned with 00 BUCK ,those knockers of this round have obviously never used it.
I've personally shot pigs,goats ,donkey and scrub cattle with this round and put them all down.

I loaded some 410 2 1/2 inch cartriges with3 x 36 cal round balls and shot cattle at close range a while ago with a one shot one kill.

00Buck is 330 diameter.

As for shooting leopard from a hide on a bait,IMHO it would be more exciting going to the local shooting gallery.
