..... which also turns the M700 WSM from a balky feeder (at BEST; my donor would literally sometimes not feed, period!) to an absolute slick-as-snot joy to cycle. The tradeoff is going from 3 rounds in the belly to two. The WSM Wyatt's extended box does require a minor modification to the action.
The 700 is just not an ideal WSM platform, hence the SAUM's. The M70 or Kimber are far better platforms. 2 down is a zero to me.
