I got some 405 g RNFP. I don't know that I want to put that big of a charge in there :-)Check your bullet profiles, my Marlin was unhappy with anything but round nose flat point. Midway had a sale on 400 grain jacketed soft point Remington's, it liked these, but over a big charge of 3031 a session made me think I needed to reset my fillings.
Got all my 223 loaded. Now it's time to fill the 9mm reserves and maybe some blackout before switching back to 40 for next year's season.
