Most accurate? 22-250 or the new Ruger 204? OR other suggestions?

Usually for sale like a benchrest.com has them in the classifieds, possibly other online gun auctions you may come across something in the 6mmBR. No, your biggies, ie. Remington, Browning, Winchester, Ruger, do not at this point. So it is only available from someone that custom made one or from Cooper Firearms also. Gunsmith can build you one to your specifications ie. barrel twist (what bullet weight you prefer) and length of barrel, stock, action, trigger etc. Almost endless choices. Do you want to start at the top or work your way up... Good luck.
