16ga and 20ga 3in mag

[1775usmarine]

I picked up 2 old school lee loaders for 16 ga and 3in mag 20ga dirt cheap. Looking at the charts provided I see things have changed since they came out. I would like to be able to use the same powder for both rounds. I seen unique is good for both albeit 2 3/4 20ga. Will unique be a good choice still to do 3in mag shells? I have a manual that has limited shotgun reloading info and plan on getting one just for shotgun reloading. I'm not a high volume shooter so making 10-20 rounds by hand doesn't bother me.

In my opinion, the Lyman shotshell reloading book is money well spent if you’re getting into that.
