Barrel Contour

[G-Man WC]

Remington Sendero barrel and a Remington varmint barrel contour, what's the difference?
I thought all 700 Rem HV barrels are 1.250 at the chamber,and .820 at the muzzle and the word "Sendero" at
Rem meant [LA) long-action. Well until SAUM's came out anyway.
Looking at some pictures the Send contour looks to have more meat
at the muzzle. Is it only the contour between the aftermarket barrel makers that differs from the factory Rem contour?

Rem Sendero and Rem Varmint are the same.
There is a Rem Magnum contour that is different.
Aftermarket contours are "close", but not the same.
Even Remington contoured barrels are "close" but not the same...
