I currently have a 6 mm barrel w/ a 8 twist, and trying to decide on whether to go back with standard 243 or try one the 30 or 40 degree shouldered rounds. Of the 3 in my subject heading which one will be easier to work with and I assume that FF ing can also be accomplished with the SLR round also? Will Lapua brass or Hornady brass form w/o dounuts this way? Any input appreciated.
Thanks
