what's this talk of "trick hunts" pure rubbish I say!
A sport wishes to hunt buff with a bow & arrow fine that's their choice and the choice of a PH to hunt them or not. The "it must be a 375 or better crowd" should pull their snouts down a bit, quit puffing on those old cigars and just admit it is the hunters option and his dime.
I know when I go on safari I'm putting the good old US Greenbacks out to do it and make my intent known when booking. If a company wishes to decline me so be it another will not.
Look at Zimbabawe for example I can go there hunting buff with a bow an they don't as much as list min. draw weight to be used, let alone weight of shaft,cutting head etc.
Do I own a 458 Lott? yes I do will I use it again, no doubt but should I wish to stick a buff in the ribs with a shaft I will not consider it a "trick" I will consider it a hard won trophy that I HUNTED until I could get the proper shot angle for the weapon I am using. I do not think a shot with a .500 "at any angle" is sport hunting just to see what damage it will do...that I consider caddish!!
