Richard, what kinda rifle are you loading for? I am sorry I cannot help you out on this one. I have some full house loads (read factory level ballistics) that I shoot in a double rifle. The old double don't like anything but factory level loads though.

Actually, it is for a friend. He has a Luftwaffe drilling that is no longer collectable and is thinking of getting a vierling.

I have all sorts of information on regular loadings--nothing on reduced loads. I bet the Speer manual would have a reduced load, but I can't find my current ones.

I had a 9.3x74 at onetime and have all sorts of reloading stuff for it. May get another one day.
