OP shootbrownelk Campfire Tracker S Joined: Sep 2014 Posts: 3,460 wyoming	Anyone have any .243 loads using a Hornady 80 gr. GMX bullet? I have IMR 4064 and IMR 4350 powders. The rifle is a Remington 660 with a 1-9" twist. I load for my .308 and 30.06, but the .243 is new to me. Thanks for any help.
