6.5 SST Fire Forming Brass Recipe's

[Steved1911]

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.

52.0-53.0 RL23
54.0-55.0 H1000

130-140gr projectile of choice. I like the 130 TMK or 140 BMBs.

Thank you. I have some pulled 144 and 156 Bergers that I want to try. Do you think going a little less like 49 or 50 may work?

I would drop the 156 loads by a grain. The 144s, I would not have an issue with the weights I quoted.
Those loads are all fairly light as it is. They have been my fire forming go-to in several rifles.
