I'd say so.
I have never felt the need to either clean or oil a springer barrel over many years of shooting them. It's my belief that the small amount of lead from pellets protects the barrel. Many might advise to clean the barrel when testing different pellets, but I just shoot about twenty of the new pellets to "condition" the barrel and then get on with testing. And to no detriment, as far as I can tell.
Incidentally, John, what do you personally use for the lubrication of the leather seals on your vintage and classic rifles? These days, most of my (more modern) springers run synthetic seals, but I may go back to leather on one of my older 35s and I have an older Diana 24D that runs a leather seal? Guessing you use Neatsfoot?
Looking forward to reading many more of your most excellent and informative articles.
