I'm a retired plumber...
2. My back-up PH uses a Cannon (digital)
3. Them that can, do. Them that can't, talk.
4. African old male Cape Buffalo are the nastiest bovines I've ever met. All that talk ain't BS.
It's hard for you, who have never been there to have an opinion about what you know absolute zero personally. I admit I've only hunted three of them, however, I do have a pretty good opinion of just how bad tempered they are.

Ps. For sambar I wouldn't waste a .458 Lott round. I have no experience, haven't been there, don't know what they act like - in general, I'm just like you ... But I think my .257 Weatherby would damn near be overkill. (Look it up before you type.)
