Well finally something in my wheelhouse,, I use CCI 200 primers, mostly Winchester brass, Winchester 780 Supreme, and 100 grain Sierra Gamekings.
My daughter's Mark X loves this combination, and sometimes when I shoot my best I can get a 5 round group les than 5/8's inch ay 100yds. It's a pleasure to shoot and clean up isn't bad at all.
Recently I have been working up a load with IMR 7828, and 95 grn Ballistic Tips, with continuing success.
Thanks for coming!
