One more thing Shakari;

You are to be commended for creative-thinking in setting up your shooting "game". Some scoff at such things, but in this day and age when many hunters have very little experience with their hands inside a critter, any such practice is very good lesson-learning.

I have spoken to hunters who really have no idea what is inside an animal. They gut their critter in the field in the dark, paying as little attention to the process as they can because it is "gross" and then get the butcher to do the rest, sometimes including skinning.

My kids grew up under the butchering pole so-to-speak, and were involved in agricultural clubs and such and found all that experience very helpful when they started hunting.

Also, food for thought...

A fellow I know used a US M1 .30 Carbine for years on cougar {"lion" around here} and others I've spoken to also had great things to say about that rifle for cougar hunting. Would probably make a pretty good leopard gun to for followups. Seems anemic, I know, but for close fast shooting, using soft point ammo, the round is deadly, and the guns handle like a good shotgun. I doubt they are available or even legal where the leopard are, but just a thought...
