I am in the process of building a .338 win. mag. when it is completed I would like to shoot some cast bullets in it.My reason for doing this is so that I can get in some target shooting with low recoil reduced loads.I do not cast my own.Does anyone have any favorites for the .338 that would work well for this purpose?I also mite like to try this gun on deer and black bear with a cast bullet, any thoughts on this?
