32 Cal.
A short while back I was shooting and cleaning a new to me percussion ML in .54 cal manufactured in the early 80's, and was kinda alarmed at the amount of, what I would now call "build up" in the barrel, that seemed to be old lube of some kind.
It would not be removed by cleaning in my usual hot water/dawn soap procedure.
It was clearly visible in the bore as light tan/brown colored streaks in the crevices of the inside corners of the riffling grooves.
So... I got aggressive with it, with some serious cleaner/degreaser chemicals and scrub brushes ect.
Took some effort but finally got it all out and just for good measure gave the bore a good scrub/polish with scotchbite pads and fine steel wool.
Doesn't seem to have hurt anything accuracy wise but I'm still in load development mode.
Now... I have been informed that there is no such thing as "seasoning" in a ML barrel.
And I would agree, I mean seasoning is what you do to meat before ya grill it, right?
But... I have this tube of Hornady lube from probably 25 plus years ago that says different...
