Sliver,
My goal was finding a low-velocity Hornet load to somewhat duplicate .22 rimfire.
I settled on 2 grains of Red-Dot measured with the smallest Lee plastic powder dipper; no rocket science here. I neck-size my nickel plated cases with a Lee collet die and place them in a homemade wooden 50 case holder. I use a custom, lathe-turned, plastic funnel to pour the powder directly into the small rifle-primed case from the dipper. I leave a hole between full and empty cases in the holder so I don't double-charge. I then seat a 45 grain Sierra round-nose bullet (I used to use Winchester RN bullets but they quit making them).
Shoots fine out to 50 yards or so in my barreled drilling insert and the neck-sized cases last forever.
For full power loads, I find the Hornday factory ammo is very accurate, often making one of those "iffy" Hornet barrels settle down considerably.
Of course, you are on your own liability-wise with this information; good shooting.
