Bobjoe I'm a little envious of your Buffalo tag ,lucky man ...I load my 86 carbine (Browning ) with the 350 grain Hornady over 4198 for around 2100 fps ,its my Moose rifle and it really knocks the good right out of 'em ...over the bench shes a little rough ,but hunting you'll never know it went off,the 400 grain bullets really give you a root for sure I used them exclusively before I discovered the Hornady's ...and I changed over because of the tougher construction of the Hornady.The Woodleigh is supposed to be a great bullet from I've read but I've never had the chance to use it ,but that will change when the next tag comes round .
Good luck!
