There are a lot of answers that will work but I had a 1.75-6x Leup with a 4a reticle (Leup's) on my .375 that worked perfectly for me. In fact I'd say that heavy reticle was more significant to me than the power of the scope; it stood out bold against the grey-brown of the winter Namibian bush. And, my furtherest shot was about 200 yds on a greater kudu through a series of openings in the bush. Generally, where I hunted, shots tended to be on the short side to just beyond that.
