45-70. No other buffalo rounds out there! Or use a recurve or longbow.

Really you don't need anything that big anyways for Bison. The shots are usually close range so anything from 50 cal ML to about any centerfire 308 and up. I am sure you could use evensmaller but I had to start somewhere. One ranch in TX only allows ML or archery.

My dad would love to go archery, but someone stated that the buff hunts in WY only allow rifle.....no MZ, or bow....and after checking the PnY record books, there isn't 1 from wyoming....so sounds right, which does stink, but I think as someone else stated, they want these things killed, not wounded etc....

Personally walking up to one at 25yds doesn't sound like fun, hopefully it won't be a hunt like that.

Considering the role the bison's played in American history and legend, I think I'd have to look at this hunt as an excuse to buy myself a Sharps or Springfield replicain .45-70.

We're not talking about Cape Buffalo here, though. A cannon isn't required to bring one down, a well-placed shot from your elk/moose rifle will do. Both the guys I know who hunted bison in the last couple years did it with a .30-06and .300 Win Mag, respectively. Since I already have a .375, I'd be inclined to take it, but wouldn't feel undergunned if all I had was my .30-06.

45-70 great performance out of the new hornady rounds

I saw a guy drop a buffalon on tv with a neck shot from a .30-30, then from one outfitters website I've seen about how much lead some of these guys can soak up, paraphasing him, he personally had seen a buff take 5 shots from a .300 win mag, all within the size of a small plate, then to hand the client his .375 where he put 3 more in him....

My cousin I know put 3 in his buff with a .338 win mag before having him drop.

To me big and slow sounds better, the .458lott while faster than the .45-70 is much bigger and slower than the other 2. I suppose by the time the hunt, if it happens, rolls around I'll have a much better idea of how the hunt should go.

I have a neighbor that has a few bison hunts every year. He told me the fasted kill on a buffalo he saw personally was a kid shooting a 243. He said the buff was anchored immediately and didn't even twitch. He's never had a guy shoot one with a bow before, so once he decides to butcher another one he is going to let me dispatch it with my bow.

I think in Wyo, they call for nothing under .270 caliber.

I think all 3 though will get the job done so I guess what's the worry.

45-70!!! What else is there. I have never shot a Bison, but I sure would like to. Plus the meat is excellent, and there is plenty of it. Tom.

I wouldn't feel one bit undergunned with my 8x57jrs.... And a properly loaded 30-06 will tip them right over too...
