Between my father and I, we’ve had five magnum M7 rifles with the mag contour barrel. All have shot well enough. Three 7mm SAUMs, a .300SAUM, and a .350RM. Not sure I’d want a 20” WSM, due to blast.
That plus IMHO at least with every Remington I have used or bought in a WSM package they do not feed smoothly. The polar opposite of a Vanguard, Sako, Browning Abolt or Tikka which I have tried in the WSM . The Sako being the smoothest of the bunch
