This is getting interesting...... A few questions:-

What do you consider a bath of shot?

What do you consider the right distance to shoot in these situations?

How much time do you consider is available in a Leopard charge situation?

How quickly can you get those 3 shots you mention off?

Do you really think that when a Leopard charges, you have time to get 3 shots off?

How many 000 shot pellets do you think are in even the longest carridge?

What do you think the shot spread would be at 5, 10 & 15 feet?

How large would the holes be in the shot pattern at those ranges?

What velocity do you think the shot pellets would be moving at the muzzle?

What speed & energy do you think they would retain at the afore- mentioned distances?

Can you please define what you mean by a a top qualified PH and how many of them do you know and who are they and how many of them have you hunted with and where and for what?

What do you mean by invisible solid glass?

I just can't see how a 000 shot shell can provide a bath of shot or an invisible wall of glass.

I'm not trying to tell anyone else what to use in these situations, as I said earlier, I;n just expressing a personal opinion based on personal experience.
