It wouldn't be .257 Roberts, but rather the .257 Roberts necked up to
6.5mm, which was the gun's original caliber. The originator of this
wildcat just ran a .257 Roberts reamer into the barrel of his Arisaka
and necked up the brass. Probably used a light charge of fast powder
and Cream of Wheat to do the job. I believe Ackley has this listed in
his book on wildcats. In any case, the O.P. isn't going to be using
off-the-shelf ammo for it. A chamber cast is going to be needed and a
set of custom dies made, I believe Huntington still does this. It'll
cost more than the gun is probably worth, but about the only way to
get it shooting without a whole lot of messing with dies the O.P.
doesn't have. The parent case of the Roberts is the 7x57, which may
be easier to get brass for these days.

I knew a guy that had one of these conversions, he used it on mule
deer, said it was accurate.
