I'll have to agree with Lil'Gun being the "go to" powder for the Hornet. I don't have any notes on the other powders I have tried, but I get good accuracy and good velocity with Lil'Gun with 35-55 gr bullets (the 60 gr V-Max wouldn't stablize at Hornet velocities, even with a 1 in 12" barrel).
I use 13.5 gr of Lil'Gun with a 40 gr V-Max, CCI 400 in R-P brass with an OAL of 1.935" I can use that OAL, because the 20" Handi rifle I use has a very long throat. It produces around 2750 fps which is pretty effective on crows and etc.
R-P brass will hold more powder than Win brass and I get get better accuracy with R-P.
Lee collet neck size dies will help prolong brass life and it's probably more accurate than FL sizing.
The heavier bullets didn't give me the same degree of accuracy I got with the 40 gr V-Max, but I was just playing with them anyway!
