Friends- I have a rifle that I am strongly considering rechambering to .300 RUM from .300 Weatherby. It seems intuitive to me that it would be a really easy rechamber job save and accept for cleaning up the freebore. Any comments or suggestions? I know that I will need to change out magazine box and alter feed rails? I just think that the .300 RUM is a better long range hunting round than the .300 Weatherby. What are your thoughts? Thanks in advance.
