Gunsmithing Correct way to measure barrel length?

Re: Correct way to measure barrel length?

from breech to muzzle. Easiest way is to insert cleaning rod into muzzle until it rests against the bolt face (closed bolt) and mark the rod at the muzzle.

On a Remington I measure from the gas hold on the side of the receiver to the muzzle.
Cleaning rod method is always good. They have so many uses. I use a tape measure, tight patch and a cleaning rod to check twist rates.
