From a conceptual standpoint, could a bolt-action rifle (such as a LH Win M70) originally chambered in a WSM such as 270 WSM or 300 WSM be successfully re-barrelled to a 6.5 PRC? The WSM cartridges have a rim diameter of .535" whereas the 6.5 PRC has a rim diameter of .532". Is that too much...
Condolences on the loss of your Uncle.
This is a beautiful rifle. That is one amazing piece of wood. Wishing many happy memories while shooting this unique heirloom.
Sounds like a fantastic trip and fishing experience. Congratulations on doing the research, making a plan, and following through on making "forever memories".
