Interesting Combination?

Saw an ad for an OM Ruger .44 "with a extra .45 Colt cylinder to enable it to fire .45's". Wondering how it fires .45 bullets through a .44 barrel?

Sorry - it was a Ruger Old Army with the extra cylinder.

Yup I had one a eon ago when they first came out. They might have been called a .44 but if I remember right I think it took a .452 or .454 ball. Think I still have some out in the shed. I have a original .44 New model Remington that also takes that same ball. Don't ask me why they called em .44`s.

Probably for the same reason they call .429's 44's and call .357's 38's

Blackpowder revolvers are measured to the lands of the barrel's rifling (narrowest part). Modern smokeless cartridges have since changed to a measurement of the groove (widest part).

That's the way I learned it many moons ago (40-50 years?)

So it is no longer "bore diameter?"

Bore diameter is correct. It seems my nomenclature was off! Many thanks for the correction.
