Want to shoot 180gr. XTP's from my lever gun but all my manuals start w/200grXTP's. Is it okay to use the 180gr. revolver loads?

Hornady 10th Edition lists them with rifle. 18" barrel

Blue Dot 15.0 (1,700 fps) - 18.6 (2,000 fps max)
IMR800X 14.4 (1,700 fps) - 18.8 (2,000 fps max)
VIHT N-105 16.1 (1,700 fps) - 20.4 (2,000 fps max)
AA7 17.1 (1,700 fps) - 21.2 (2,000 fps max)
VIHT N-110 20.3 (1,700 fps) - 28.0 (2,200 fps max)
Alliant 2400 21.6 (1,700 fps) - 27.5 (2,100 fps max)

As to your question, revolver loads should be safe in a rifle in good repair.
