Hornady's 6th edition manual has 7.62x25 data for the 90 grain XTP. I won't retype it here for fear of posting a typo that could lead a dangerous situation. If you have Hornady's 6th edition, check it. If not, you may be able to email Hornady for the info.
Otherwise, I'd recommend emailing the manufacturer of the powder you intend to use to get data.
