Make sure gun is unloaded to test.
Make a dowel rod just small enough to fit down the bore a few inches longer than the barrel.
Cock the hammer tilt the weapon so barrel is pointed up, insert dowel. If it falls throught the cyl good. now check all cyl's on the revolver the same way.
If it hits a bit of the cyl on the way down, that particular one is out of time.
Factory new can be slightly out of time on one or more.
Most people never notice a slight out of time because of the forcing cone on the barrel. They always wonder why out of 5 or 6 shots [depending on revolver] one is a flyer even at close ranges. Out of time on that particular cyl.
To answer your question, there is no set number of rounds for this. If it tests good, shoot it, clean it, enjoy it.
Older Smiths and Colts [police trades years ago] are still in time today after sometimes thousands of rounds.
Flipping the cyl shut [like on tv] is a sure way to get one out of time in a hurry.
