Love the 340 Wby! I used one on a Plains Game hunt in south Africa and Namibia, 210 XBT going 3200fps ( '98) rifle was formerly a 300 win Mag that I sent to Match Grade Arms. I had it built too light ( with its necessary brake it kicked the guts out of every scope I put on it. before I had to quit it ( went to the spare 300WM we took) I killed a big zebra mare, Impala, Blesbuck, and a big Namibian Gemsbuck. That rifle got rebarreled back home to a heavier barreled 338WM. Later in life, I had a factory Model 700 338 RUM and a Weatherby Vanguard custom. The 700 shot the 250PT right at 3000fps easily, and the Wby shot the 180 NAB right at 3500fps. 338 RUM and 340 Wby...same same to me! Have a ball pard!
