With 230 gr FMJ & a seating depth of 1.274, I'm getting great results out of 5.7 gr. of 231. If I bump down to 5.4 gr. and below on the powder (even with going to a deeper seating depth), the load just barely works the slide.
As you've probably gathered, seating depth has a lot to do with overall pressure the load generates. But I've got to admit, I don't know much about the XTP hollow point 230 gr. - each different style of bullet has its own ballistic coefficient - and the one you're loading for is not in my experience. I'm a FMJRN kinda guy.
