I'm about ready to start reloading for my 450 Marlin. Has anybody used either of these bullets in their 450, or 45/70? And if so what did you think of the results. Was also thinking of milling flats in some Barnes 500gr. Solids, bringing them down to approx. 475gr. with flats large enough to make them safe in a tube magazine. What do you all think?<P>Phil
