Edit: I see this information you posted came from one of Randy Wakeman's articles. Best take it with a little salt.
Depends on the barrel length with a 44 inch barrel you could burn when you push unburned powder out it not only wastes powder but the added weight actually holds down the velocity if its not burned.
To answer some thing else that was mentioned, By checking with a chronograph you can find the point of efficiency with a 250 gr bullet it is 110 gr of 777, 140 gr of Blackhorn and 130 gr of pyrodex and that is why 130 gr is faster than 150 unless you use a heavy bullet. Blackhorn will burn more more efficiently because it is a Progressive burning powder that also means if you over do it it will take a major jump in pressure.
