Hi, I'm trying to fire form some 6.5 SST brass that is the new "B" chamber brass and I have the original chamber in my gun. The brass is new ADG with 6.5 SST on it but it seems my chamber is 5tho longer. What would a good recipe to use just to form the brass with 144 Berger Hybrids (pulled) or 140 Barnes Match burners and either Magnum powder (have a ton and used for nothing own) or Staball 6.5. Any help or info would be greatly appreciated. I do have a tone of RL25 also.
