I'm new to the .22 Hornet and I have loaded some with W296, which I can find published data for. In doing research, I see in the past that Herco has been used for .22 Hornet. I have looked to no avail in finding any data for it. Currently I am shooting j-words, Speer 33 gr and a Sierra 40 gr. Any one have experience with Herco. Could it just have been for cast? Thanks for the help.
