I designed the 435 PH Express because I love big game rifles and wanted to fill a gap. I have owned 416, 450/400, 458, 458lott rifles, plus seen may other calibers take buffalo, and have nothing but praise for each rifle in its correct place. I feel the 435 PH Express will give the best of both worlds, good penetration and good stopping power. Although will have real limitations like everything else. For those knockers our there, please note I am not a big noting person after fame and glory. But a genuine damn good bloke whom would enjoy any descent hunters company around the campfire or in the feild. And yes basically it is a 425WR, of which I do not wish to build, but rather to own a modern version. Take care, Graham.
