Looking at the 50th edition of the Lyman’s manual and 11th edition of the Hornady manual, the Lyman lists a max charge of 45gr of H110 for the 300 gr FXT for a velocity of 2098 FPS.
Hornady list 51.4 grs with the same bullet at a velocity of 2000 fps.
Why the difference?
Both load uses large rifle primers.
I’ve been loading 50 grs of H110 with a large magnum rifle primer.
