cleaning
Alas.... I've been cleaning my guns wrong all these years. Been using segmented, brass cleaning rods, and other horrible things like Hoppes, brass brushes, oil, and cotton patches in all of my gun barrels since I was a kid. Also regularly use several of those horrible little aluminum rods S&W shipped with their handguns.
Admittedly, I know very little about metallurgy, but it seems to me careful use of a clean, high quality brass cleaning rod, segmented or no, to clean a barrel would not cause any harm.
Frankly, all the hype about one piece, coated gun cleaning rods seems like nothing more than a marketing ploy. Saw a Tipton one piece, carbon fiber cleaning rod the other day that was $75.00. What?
I'm just old school and stupid, I guess.
