Fiftydriver, this is my firt post and new to the long range hunting thing. I have a weatherby 338-378 mark 5. its a nice rig but I can only groop about 7.5 in. in 500 yards. I know pretty pathetic. It has a loupold 4.5x14 scope on it right now. Ive read about the 338kahn and am interested to know what would be involved to transform what i have into 338kahn. keeping in mind that this would mostly be a hunting rig. can you give me an idea on cost? I allready have the reloading set up for the 338-378 so what else would I need? Ive only reloaded for factory loades and never attemped any fancy wildcat loads so im not familiar with the process or extra dies needed. Thanks
