Bouldersmith, sensational rifle in a super calibre. Unfortunately it is not that popular and therefore the brass is hard to get and expensive. Many times I have thought of building a Ruger No.1 in 300 Flanged and seeing your rifle now, I have made up my mind. I would also love a Kipplaufbuechse in 8x75RS. The 300 Flanged with a 180 grain projectile and the 8x75RS with 220 grain. Brass is available from Bertam in both cases.
