We have a very senior member on a Canadian forum. Among his many credentuals; he has worked for ammo manufacturers, worked for a powder manufacturer at a senior level; spent decades custom loading ammo for target clubs and police and military contracts. He sort of laughs at the tumbling loaded ammo question because factory ammo is tumbled. You know the tumbling
might knock the coating off argument? Turns out that the coating is tumbled on in the first place. Cool cat, with a insight that just can't be guessed.
I quit worrying about it after talking to him. I'll clean my match ammo after loaded and never give it a second thought.
