Alliant Power Pro Varmint burn rate

[short round]

Trying to find burn rate for power pro Varmint. Thinking about trying it in 6 PPC with 68 gr bullets. Has any one tried it in 6ppc & what would be starting load?

[scope eye]

ProVarmint falls somewhere in between RL15 and Varget, so with a 68gr bullet you can run as much as you can fit into the case, and not even be close to pressure signs.
