Cheers,
From talking to the "old timers" I've met in the Rockies and Alaska - they never expected to do a "one shot - one kill" with a Grizz. The first shot was ALWAYS to break them down. That means disableing(sp?) the bear to where you had a chance to have a second shot.
What they told me was always shoot for the shoulder, and then try for a head shot, from behind, or a heart shot.
If it took two shots to stop the bear, then you shot the other shoulder. It wasn't a pretty kill, but it was a kill.
When I flew up in AK, I always had a "shot-gunner" with me - and most of them felt that the first thing they needed to do was blow "sh*t" into the bear's eyes to disable it. What most of them talked about was "barking" them with the first round - which gave them the time to get into position to do a another shot. Now these "boys" were using the hotest round made for 12 guages - so - I listened, and then quitely hid my .357 without anyone seeing me do it.
Long, long time ago, the fella that got me into BP, wanted more than anything else in the world - to take an AK brownie with a smoke pole. We shot for years together, and one day, he approached me about "shooting second" for him on a hunt. He had the guides set up, the permits, everything. All I had to do was purchase my airline tickets and we were a go.
Well, after a couple of beers, I finally asked the MOST important question -"Kenny, if you've already shot the bear and it's my turn to shoot - who do I shoot - you or the bear?
I changed helicopter company's about then and never got to do the hunt he wanted - so I don't know how it went. BUT, I remember all that advise - about "breaking them down" with the first shot.
I think it's something that you should keep in mind! I know that you don't want to end up with all the pepper spray and bear bells that's already in his stomach.
With that in mind - a 45/70 should work - it sure beats the 45 Hawken we were gonna' carry!
It ain't a pretty kill, but it's a KILL.
Gentle winds,
