Fireforming .32-20's

I picked up a bunch of ".25-20's" from a guy a while back. He was candid that some were necked down .32-20's and I was OK with that. Come to find out the necked down ones won't reliably chamber in my rifles ('94 Marlin and Husky bolt). I did not investigate too deeply but I suppose the neck is too thick. Anyway, I think the most reliable way to restore them to .32-20 is to fireform with some corn meal and a wad of TP, Question is: What charge of BE? I'm thinking in the 2-3 grains neighborhood. Whadya think?

Thanks!
