I was always a fan of the 6MM Rem. Never having one I now question if it is as I imagine it to be. I have never been keen on the .243Win but have no reason why. I have a Model Seven Rem and wish to rebarrel it into a 6MM something and now have entertained the .243AI. I believe it has a longer neck closer to that of a 6MM Rem. Give me your thought?????????
