That is good performance. The Winchester Power Points were always a favourite for me - seemed to work properly on most game, most calibres. In the .375H&H - there are few 270gr. that perform as well.

An old friend of mine switched me to them for my BRNO. He showed me at least 15 that he'd kept from Elk in Montana when he guided at the TBar3 dude ranch (I think that was the ranch name). Every PP Winchester looked identical to the others & to the one pictured above, with the same or barely more shank and every one was dug out from under the hide on the offside after the double lung shot.
