I don't personally have anything to benefit you, however I suggest you heed the advice given in the past, by those who know what they are talking about, and unfortunately is true for 1911fan, those who are no longer around to shine light on your situation directly.

You do not need a 155 Howitzer or the latest super magnum. You need a bullet that can make its way through hide, a rib, and punch through heart or lung, that is all."
There are some grain weights given in the thread I put above. As to bullet type, pick one of the many that will penetrate a bit and then reliably expand. You'll note "ballistic tip" bullets were not well looked upon in threads like the one above.
That should get you started. Wish he were here, he was a big Savage guy. You'll find a lot of posts related to that caliber by him if you use the search function. I know there are a couple other guys here who have been around the caliber a fair bit too.
