If ya still don't like 'er, rebarrel.
Re-stocking a Mark V for a heavy barrel contour (i.e. heavier than #4)..the choices are a bit limited. McMillan and Bell Carlson's barrel channels will only support a #4 or smaller for their sporter style stock. McMillian will inlet a A-5 for #4 barrel channel or larger w/Mark V action, but it'll be 5 month wait:(
Weatherby will sell you the Threat Response Custom Stock that Bell Carlson makes for them for $850! (ouch!), but it again is inletted for a #4 barrel channel contour.
Lone Wolf or MPI can make you a custom synthetic sporter or tactical style stock.
When I spoke with Manners, they didn't inlet for the Mark V action :(
Joel Russo makes some works of art if you can consider a laminate wood stock.
Have you seen Broz's Mark V Lapua?
My New Long Range .338 Lapua
Drop him a PM, and he'll tell you what his stick can do for long range shooting.
JE Custom is another very knowledgeable Weatherby guy, give him a PM with your questions regarding what you want, and where you can go with the Mark V action.
Most factory Senderos shoot accurate as well right out of the box. I had one that shot sub 1" center to center groups at 100 yds with factory ammo, and down to .5" after handloading.
Hope that helped. Good luck!
