No matter the caliber, with a T/C, you can load them as long as your action will close. Just work up the data each time you change the OAL as pressure can and will change, often very quickly.

gunoil,

I don't know that this is pertinent to your situation, but the .30 Herrett needs to be fire formed to your chamber, and resized so that the case headspaces on the shoulder, rather than the rim. Set your sizing die so that a slight resistance is felt when closing the action. Accuracy, and pressure should stabilize when the case is sized this way!

Good shootin' to ya!
