I'm new here so bear with me if I display some degree of ignorance in my first-ever post! I'm curious if anyone shoots cast bullets in their double-rifles. I am considering a .450/.400 3 1/4 for a 2013-or-14 DG hunt and am wondering about the idea of practicing with it here at my local range to build up some experience with the rifle. I reload for all my other hunting rifles and firearms that I shoot consistently, so it's a thought for the .450/.400, but I'm open to higher knowledge!!
