different powders produce different velocities and recoil.I'm reloading 50 ae and 440 corbon rounds.the h110 really kicks at 29 grains,1400-1700 fps.
the h4227 powder puts out around 1300 fps but is much smoother and more accurate in my 50.
my most accurate loads are between 1-2 grains below maximum published charges.
I use hodgdon powder exclusively,they are clean burning,and very accurate and reliable.
