not sure if this is much help but there is a whole thread about them over on snipers hide. warning its 13 pages long and i haven't read the whole thing but there is some good info in there.
friend of mine owns one in 6.5prc. It shoots ok with factory ammo. With the assistance of Whidden Gunworks dies and some careful sorting and prep of the (questionable) hornady brass, it will deliver 5 rounds under and inch even on a bad day and has shot multiple .5 inch groups. Just keep in mind that the barrels are not terribly heavy and that a large powder bottle like the PRC is not going to deliver as tight a grouping as the smaller cases in a gun of the same weight.
The bolt design is sort of unique but that isn't a bad thing in and of itself. I looked into them very hard (i would have paid 60% of street price, so I was curious) but once I got into the details, I was less enthused. The bolt is of larger than normal diameter (again, not a bad thing in and of itself, but it means a custom made bore guide and a custom made action wrench are in order), the action is a push feed with plunger ejector (a strike to me after my experiences with CRF actions), and Seekins would not provide a price, part number, or even a lead time on replacement "pre fit" barrels. The last part really shot it in the head. One of their selling points was a "no gunsmith required" rebarrel option. When that isn't on the table from go, I get worried. When the mfg is squirrelly about answering questions, I become disinterested.
Take my opinions with a big grain of salt. I am a self-admitted rifle snob.
