JB,

I'm not mixing the Nu-Finish in with the Lyman. I replaced the Lyman corn cob with medium coarse, untreated walnut shells and added the Nu-Finish to that.

I use carbide dies for all of my pistol resizing. The 41 Mag and 44 Spec brass I resized seemed to be a little harder to size with the Nu Finish walnut shells vs. the Lyman corn cob media.

However, I just resized a batch of .45 ACP and they seemed just as easy as before. Go figure.
