I have more 600/660 builds, 4, than I do factory specs rifles, 3.

I just did a 660 parts gun:

660 action, via Drover's factory specs 308.
700 ADL alloy trigger guard, via the parts bin.
700 BDL magazine box, via the parts bin.
700 DM MR 22" 260 barrel, via DennisinAZ
McM MR swirley, via Rick Bin

I don't like the way the 700 ADL trigger guard fits backward on McM's 600/660 inlet, so I reversed it. I used a small piece of steel to make a spacer between the bottom of the 700 BDL magazine box and the floor of the stock. I d&t a hole for the front trigger guard screw in the rear spacer. I don't like how the 600/660 trigger blade sits forward in the trigger guard bow, so I'm going to replace it with a 700 trigger.

I have not done a SAUM or WSM in a 600/660, my current builds are in 257 Roberts, 260 (x2), and 308. I'd like to find another 600/660 donor action with a 0.473" bolt face, 'cause I have another McM Rem MR stock inletted for the 600/660 action and plenty of other parts to make another complete rifle.
