    I’ve owned a 6.5STW since it was first introduced by Layne and needed to rebarrel after many years of great performance on game. Weatherby introduced the 6.5-300 at just the right time so I chose that chamber since STW brass was getting hard to come by. So far in load development it easily makes the specified velocities, and accuracy looks encouraging. My barrel likes the 127 grain Barnes LRX bullet the best so far. Barnes lists US869 as the preferred powder and my results indicate this is probably true. I may work up some Retumbo loads as well just to see but there really is no need to do so.

    I had one built off a vanguard action that was originally a 300wby. While its a 1″ gun with the 127 and 130gr factory loads its a single hole cluster with 130gr berger vld hunting bullets. Giving my 26 nosler to the boy and keeping this for myself, its a winner.
