My thoughts if I was to take a .45-70 back to Africa for dangerous game[cape buffalo]. I would take a standard 1895, with a 22" barrel[to get the velocity needed]. I'd modify it, with a mag tube extension to get the maximum number of rounds I could get in the gun. I'd put a quick detach leupold 1.75 x 6 power scope on board. The load I would use is the following.
Belt Mtn. punch bullet 400 gr.[solid], loaded to approx 2000 fps.
For a soft, I'd use a Barnes original, 400 gr., or if nosler had one, a 400 gr. nosler partition, loaded to the same 2000 fps. Sight the gun in with both, and be able to use the softs on plains game. If the ph insisted, hit the buff with a soft, followed by6/7 of the punch bullet solids. Use the softs on whatever else I was hunting. Next trip[if ever], here is my wish list.
Cape buff
bush pig
eland
bushbuck
waterbuck
another big wart hog.
I probably wouldn't buy a "big gun"[you decide the cal.], because I know if I ever get back, it would be the last trip. My .45-70 would be useful to me, at home. JMHO.
