Missouri 475 Thumper 340 RNFP and H110

Checked Hodgdon and they couldn’t help, I have trailboss but wanted to work with the 110/296 I have as well. Anyone use this particular round in 480 Ruger?

Hodgdon list the 325 grain at 25.0-27.0 grains of H110 and the 355 grain at 26.0-27.0 grains. I would imagine you would be good with a 340 at 26.0-27.0 for sure.
