Gunsmithing AIAW 338 Barrel diameter?

[Victor Co Heather]

Can anyone mic ther 338 Super Magnum and tell me what the diameter is of the barrel directly below the muzzle break?

Or does anyone know what the barrel diameter is under the break (is there a shoulder where the break sits? like an FTE?)

Thanks,
MV

I had this answered by Mile High Shooting. Big thanks to Adam, their armorer!

The stepdown is .832" on the factory AI 338SM brake.
