The Win.70 is the plain jane. 338 Win. Mag. opened up to .375,no fireforming involved. JES does a nice job with the rebore and puts a sensible throat length that is appropriate for the loaded rounds.
I regret that I did not checkup with the skinners in regards to penetration when they dug the Hornays out of the buffalo.I think they gave adequate penetration but would have liked more.If there was a next time I would try some 450 gr. Swift A Frames .
The skinners said the lungs were shot up fairly well and
the bull didn't have long to live. I wasn't very proud of my
shooting but this could have been a bull that needed a lot of killing.
Incidentally, our dust up with this bull happened a day or two after the resident hunter was killed by a bull and the PH wounded.
Glad we didn't add to the statistics!
