Why use all that slow burning powder for few if any gain in velocity when faster burning powders will do the same with lighter charges?
A fast burning powder will produce much higher pressures to produce the same velocities. That works okay if you are not after higher speeds. At high velocities you'll have excessive pressures.
Understood, but my point is, if one can get the same velocity with 10 grs. of Blue Dot (below max load)as with 17 gr. of H110, why use H110?
