A little off the topic, but in the Feb edition of African Outfitter mag, there is an article regarding big bore wildcats, with the author very firmly saying that he (and apparently most African PH's??) are now saying that anything big driven at 2400 fps or over is now bad news, slow it down to 2150 fps or so and everything works better.
I'll have to dig it up and have another closer read of it.
Basically he is saying that there was nothing wrong with the ballistics of the old days, and pushing bullets over their recommended speeds was a recipe for disaster.
I do recall however, the article seemed very opinionated!
