Great guys a little further down the Tanana River from me. I like following their adventures.

Anyhow,
Right around 11:43 of this video, the shooting begins.

Bull is called in close. Takes 2 220 grain woodlieghs from a 30-06. Good kill shots, bull still gets up and runs. 2 more 220 grain woodleighs, still not dead. Finally finishes him off with a revolver. No biggie, as it was a land-based hunt.

Using the 358 win/275 grain, or a 9.3x62/300 grain, or even a 41-9.3x62/350 grain, never needed more than one or two shots to anchor the big rut-raged bulls.

In my way of hunting, always river/creek side, it's critical to anchor them. Recovery is dangerous if they die in the swift river or in a muskeg swamp.

If a monster bull is in your forecast, Don't overlook those nice medium bores:

358 winchester, 338 rcm, 338 win mag, 375 ruger, 375 h&h, 9.3x62 Mauser, 338-06, 35 whelen
