I have a Marlin 1895 in 45/70 that I would recommend for such a game. I have a scope on mine but depending on what you're doing and the conditions you're most likely to encounter that might not be necessary. Out to 200 shouldn't be an issue.

45-70 will the job but for a little better distance then I would go for a 444 marlin.  It would be great up to 200 yards.

x3 on the 45/70

thanks for the input guys... was going to go buy a rifle but think ill wait til the grand opening of cabelas.. im hoping they have a few good deals... and i am definitely leaning towards the 45/70 or the 444 marlin

To me a bush gun is a lot less than 200 yards.  If I am going in the bush I will take my model 94 30-30 with 170 grain soft points and if I am sticking to cutlines and cut blocks I carry my Win .270

By far most of my shots are at under 100 yards anyways.

If I was buying a new bush gun it would probably be a 45-70 as well.

yeah i actually bought a .444 on contractor night at cabelas on the 3rd, a day b4 grand opening... got a smokin deal on it... i took it out last weekend and sighted it in and man am i impressed with it...  i thought the recoil was going to be much higher but my 7mm kicks harder... also at 200 yards after all was said and done i put 10 shots out of 15 into the yellow on an archery target... the rest werent far off and i think its because my barrel was a little warm...good enough for this guy

also got a 12 gauge remi wingmaster and a .410 dirt cheap out of the gun library at cabelas... i paid $55 for the .410 wich is also an older remington

I have a Savage 99 in .300 savage and another in .308.  They are pretty decent "bush guns"
I also have a Win. M100 in ,284 and another in .308.  They will do.
And a Rem. 7600 pump in .35 whelen.  Works.

Dick's Browning would be a good one.

A 308 Winchester will never let a guy down.
