There's 36 grain data on Hodgdon's site, but 40 grain data will do. One to 3 grains wont matter, You don't need maker specific data either.
The 1 in 9 twist might give you a headache though. Nothing dangerous. Just might not stabilize those wee bullets well.
You might want to check the diameters too. The Hornet doesn't use the same diameter as .223. Only a thou different though.
