[QUOTE="MudRunner2005, post: 1529260, member: 12995"] Unfortunately the .257, .270, & 7mm Wby rifles have a magazine block plate in them, which limits the OAL length. If you had started with a .300 Wby rifle, it would not have the shorter mag box and follower, and would be a better donor for anything longer/larger than the 7mm Wby & 7mm RM. As for the ballistic comment... I say that because I have heard my whole life people touting that the 7mm Wby is supreme in velocity to the 7 Rem Mag because of biased reloading manuals and some magical properties bestowed on it by the Weatherby supporters, but in real-world testing where chronographs are relatively affordable for the common man, this has proven to be a misconception. The 7mm RemMag has proven that despite the slightly higher case capacity of the 7mm Wby, they are nearly ballistic twins. So, in the name of trying to dispel ancient myths, I like people to know that if they are looking for a cheaper and more common alternative with a better designed SAAMI reamer (less freebore), they won't be giving up anything by going to the 7mm RemMag.
