Shilen's LV Light Varmint contour is .840 at the muzzle and 1.220 at the rear and a standard Remington Sendero/Varmint contour is .830 on the end and 1.250 at the lug. Not exactly what you are looking for, but they're close. gun)
All the manufactures I've looked at have a contour lay out page illustrating all their offered dimensions. Have you even tried going to a barrel maker's website and researching this at all?
