Re: 7MM WSM - LA or SA with an extended mag box ...?
It's interesting that you list the WSM as being over .130" longer than the SAUM but the capacity is 8gr less? [img]images/icons/confused.gif[/img]
Possibly a type-0??
The 176 Cauterucio is 1.485".
Just looking over the 7/270 wsm reamer plan and figuring a throat length for the 176, I can't see how you keep those bullets above the neck/shoulder junction in a Wyatt box, even with the lighter bullets.
The 700 rails for the Ultramag feed the WSM perfectly, that's the way I'd go, cheaper and plenty long in the box at 3.66".
