Over a discussion of Dewey rods which I own, I told a guy that using a military steel rod was foolish since the rubbing on the sides would ruin the barrel.
He claimed it was impossible since barrels are “just as hard as a ball bearing”.
That’s when the conversation stopped.
“That’s when the conversation stopped.”
Yep. No sense arguing with fools. Having machined MANY custom barrels, I can tell you that barrels are just another steel alloy.
