RE: Pressure Problem for .22 Hornet?
M-43.....nice gun....
The Hornet has the discomfort of being overloaded often.....people really want more from it than it offers and load to max and beyond...you're in good shape starting with that load and a 50 grain bullet. My manual lists 11.7 grains as max and you're well below that.
H lil'gun is a fine powder for the Hornet as well
Don't camp on the max COL unless it's the longest COL your magazine will hold. You should try to get the bullet seated one diameter if you can and then let your magazine dictate the rest.....as long as you don't stuff the bullet into the lands of the rifling.....
