Yeah, Skid. Hence my thoughts of taking it one step further to create a bolt gun with a handful of interchangeable barrels. Using a 99 barrel by threading it in "normal" tight as a simple replacement for a worn out barrel is one thing, setting the gun up with multiple different caliber barrels in a hand-tight scenario is quite another.
I must be nuts to consider building a swap barrel system on a collectible 94 year old platform. Anybody got an orphan 1920 action lying around? Ha ha.
Something else I never had reason to think about: what about the barrels on the 40/45s? Don't tell me they used 99 barrels too. (I don't own a 40 to compare.)
