I was thinking really hard about having my late father's 7mm Mag rebarreled to 257 Wby since I already have a 7mm Mag. Decided not to because I can load the 7mm with a 139 gr Hornady and get virtually the same performance. So I'm going to give my father's old rifle (it was made in 1963) to my nephew with the stipulation that he has to shoot at least one deer with it before he thinks about retiring it.
