Barrel Leade Measurement

[ES13Raven]

Hi,

Can a couple of you please measure the Leade / Chamber / Throat of an stock SP-01 or SP01 Shadow barrel?

I want to check if all / most barrels have the same measurement before reaming.

Please measure with a micrometer from the left side of the breach face to the Leade as shown in this picture:

Thanks!

What you want is the distance from the breech to the chamber ledge, or the headspace distance. Is that correct ?

Yes this distance here, straight down the barrel.
