I've never loaded for a semiauto before - any secrets or tips I should know?
Seat and crimp in separate steps with any cast bullet loads.
If you're thinking for that practice load to be loaded mild like the 40 S&W, expect POI to be different than the full power load. Personally I just use the same bullet and load all the time in my 10mm - a 200gr from a Mihec mold at 1350 fps.
Do you cast your own bullets?
Do NOT use that Lee factory crimp die for cast bullet loads, regardless whether they are coated or wax lubed. It sizes the bullet down, which is one of the worst things you can do with cast bullets.
