700ML Conversion Question

[dannoboone]

Does anyone know how far the end of the BP protrudes out of the
end of the barrel? Or is it even with the end of the barrel?

On my McGowan conversion it is even with the end

On mine it's out a little.

The barrel theaded section length may vary slightly, the best measurement is 1.840" from the recoil lug shoulder of the barrel to the tip of the breechplug (primer end) if using the .186" lug. At that spec you are likely to need breechplug work on the primer end, see the headspacing tutorial.
