The original Wby Varmintmaster chambered for the 224 Wby and 22/250 had 6 lugs, 2 rows of 3 as opposed to 3 rows of 3 on the full size action.

Wby discontinued the Varmintmaster and lengthened the action and that lengthened action is used for Mark Vs in 270, 30/06, 240 Wby and also 223, 22/250 and 243.

The Accumark also has a heavier contour barrel than the Wby Deluxe in calibres from 340 Wby and down. The Accumark uses the same contour (except it is a fluted barrel) as what the Wby Deluxe uses in 378 and 416. Deluxes made as Product Upgrades in 30/378 and 338/378 also have the same contour as the Deluxe in 378 and 460.

The various heavy barrel Wby Varmint rifles have the same contour as is used on the 460 Deluxe.

Wbys are also available with the Krieger cut rifling barrel via the custom shop.
