In my hands your rifle would be 5-6 MOA and I'd be crying for my mommy by the second group. Seyfried was shooting cloverleafs at 200 with his Champlin. Of course they were his loads and he's a world class shooter. Also he had the means to have the barrel replaced if it wasn't up to his standards. I've always heard the .257 WB was the best Weatherby round for all around general usage (Caribou and down) but I've always thought the .340 and the .375 Weatherby's were the rounds to own and sadly I've never owned either. I have an extensively worked on CZ 550 from a local Bench Rester that shoots 270 TSX's into cloverleafs at 2600 fps. I don't want to mess with it, and the Mcmillan does the same with 225 TTSX Barnes factory, so as much as the grass is greener, my stuff just plain works and I'll keep what I have.
