I shoot a custom chambered wildcat (6mm x 6.8 SPC) these folks sent out to me. The polygonal rifling is their major difference from other good barrel makers. It takes forever to get stuff from them.
My 6mm shoots great. You can really push loads. Short of a three or two groove bore, or even a good AR Performance 5R, you can't get much less constriction and still get superb accuracy. Cleans very easily. They build a nice barrel. $395 or so for a basic barrel seems a bit stiff but Trident Arms gets similar. But, You can get the bolt from Trident with the barrel.
For a thumper, I'm not ready to give that much for a barrel and tie up half again that much for a bolt/carrier assembly.
