"In the late 1970s, I did a three part series on the Python for American Handgunner magazine that involved days at the factory debriefing the engineers. They told me that Python bores were tapered by .001" toward the muzzle, to drive the bullet deeper into the rifling. This is, if you think about it, quite a feat of engineering. It may be one reason why for so many years, people who preferred other revolvers paid gunsmiths to install Python barrels on them, creating a "Smolt" when the tube was joined to an S&W and a "Cougar' when mated to a Ruger."
So, not magic, but quite a feat of engineering.
Wish the article said how.
Great article, thanks for posting that link.
