I have two.
Run smooth. Feed well from DBM, will supposedly run with a bdl style bottom metal but i have not gone that route. Hell for stout. I have shouldered barrels and Savage style barrels as well. Super easy to swap.
My biggest gripe is their rail height. An LRHS in the lowest picatinny rings i can find (Ferrel) still has a good half inch of air between the objective and barrel, so you are going to want as high a comb stock you can get or go adjustable cheek.
The latest version of the Mausingfield has a rail interface that would work great for ringmount. ARC makes one; they only come in Titanium and run about $750, when you can get them. Im not crazy about this version at all. Ted says itll never move but to me the whole setup looks very Rube Goldberg and is a step back in design.
I really wanted to build a 375 h&h on one of these actions but the combination of smallish ejection port and rediculous scope height has pretty much put an end to that idea.
