Tim, I hope you have a copy of the Lyman Cast Bullet Handbook at your disposal, if so just look up the 32-20 and use the top data for the bullet weight, they will be way easy on the gun and brass, and no worries. If not, Unique is a good place to start, and I can check my book and give you real loads in a PM. Ive been using Trail Boss with satisfaction for a while now, but not sure if Ive made any 30-30/32-20 equiv. loads with it, though Im sure it would work well. Id be glad to help talk you through trying this out.
