I have two... one of the first few to come off the production line in 2008, and another one built early this year (they've improved a few small areas in the interim). I should probably mention I shoot on a sponsored team, so take the following for what its worth...
The barrel is a medium Palma contour, with the final muzzle tenon for the front sight measuring ~0.750" as that is probably the most common size for such devices. Before the tenon it's ~0.830". The fore-end is a fuzz under 2.25" wide. The newer ones have better machined bolt heads (no more dished bolt faces from the tumbling/polishing following hardening), but both stocks benefited from being bedded, in my opinion.
The first one gave me fits initially (being the first few of the line, there were some stock inletting issues). Later I had started to get it shooting pretty well, but put it aside to work on other projects. More recently, I've been shooting the second one primarily as... <gasp> a Palma rifle with sling-n-irons
and it has been shooting well enough that I think I may have to put the irons on the *other* one and save this one for F/TR! I'm not nearly as hard a holder as folks like German or Jerry, but when the first ten record shots on my last 600yd string were all Xs, even on the 'big' MR-1 target with my wobbly hold... I'd say it's got some serious potential. I'm kind of curious as to what it'd do with a NF BR scope bolted on top...
YMMV,
