John,
I was interested in your comments about the 9.3 using a 250 TTSX. On my last trip I visited a very experienced PH who is a big fan of the 9.3-62 with just about any bullet. He says it is easy to shoot well with it. With that Barnes bullet loaded to modern pressures it should be more than OK.
Until the last 20 years or so most buffalo hunters relied on solids which likely accounts for the idea that the 375 is marginal. Today’s expanding monolithic bullets have dramatically changed that calculus.
