Great choice for guns. Also great choice on chamberings. I have been loading for a friend with a 270WSM in a Mod70, and appears to be very tolerant to different loads and powders. Its hard for me to get it shooting bad. You won' t gain much over the 270win as far as speed, but thats not what I would be looking for when I bought a 270WSM. I would be looking for a short action.
