FWIW, my recent edition Hornady reloading manual lists 20.1 grains of H110 as max for the 300 gr. XTP.
Listed OAL?
I'll double check when I get home and get the book in my hand. I'm aware that this bullet has 2 different cannelures and I've used both seating depths in the past. IIRC, the manual didn't specify seating it out to the longer length at this charge, I did look for that info and will look again in a little while.
