As I alluded to in the OP, these antelope were feeding on alfalfa fields. IMO there is no better table fare than an alfalfa fed antelope properly taken care of, well maybe winter wheat fed.
Moose, axis, and eland can give it some competition though.
I have recovered one 130gr GMX out of my 270. Perfect expansion. Almost used the 180gr GMX out of my 300 H&H in Africa, but the TTSX shot a little bit better, so used it instead. I would have zero issues using T/TSX, LRX or GMX interchangeably. Zero experience with the E-Tips.
