25 of H110 is over max for a 240 grain jacketed bullet. However, only by 1 grain. Manuals do vary due to them reflecting the conditions on the day of the test. Mind you, H110 isn't a recommended powder for cast bullets. At least, not on Hodgdon's site. That just means it wasn't tested.
There's a guy on Reloader's Nest using it with a 320 grain cast bullet. Only 21.5 though. Another claiming 1431 FPS with a cast 300 using 22.5 too.
