I get the feeling that I will be inherently limiting my rifle buy using cast since I am guessing most cast loads will be a lot slower than typical factory j-word loads of 2800+ FPS. Nevertheless, I am thinking that in the coming year I will want to fool around with cast for this cartridge. Is there a mold that is considered "the" boolit for 30-06? Guessing I will be doing gas checked. Is there a typical diameter to size to? Other words of wisdom? My rifle is a Tikka T3.
