Does anyone know the dimensions of the Ruger RSM barrel in 458 lott.

Stratus,
ALL of the RSM barrels are the same n the outside... what do you want to know?

23"

Sorry I wasn't real clear,

I was trying to find the the barrel's muzzle diameter. I'm trying to use that barrel as a comparison for my own build. When I handled one I thought it was too heavy. When I order my own I want it to be a tad bit smaller than the Ruger.

sure..
muzzle, ~.815
end of first taper, 1.05 more or les
