Crimp on the cannelure of the bullet and start with a load that you know is not max. Work up to your liking or till you see pressure signs, whichever is first. The case will be about full when you start and I think the bullet will touch the powder before any over pressure signs will be seen, but keep a close eye on it.
Tell us how you like this new powder.
