I actually was planning to replace the Weatherby with a 300 PRC, the Win Mag swap has me reconsidering though...The 300 Win Mag will give you 1.66 times more energy at 500 yards than your 257 WM...(1241 vs. 2066)
Your uncle's 270 gave him 1.65 times more energy at 500 yards than his 257 Roberts...(902 vs. 1497)
I'd say you and your uncle are "even up" in regards to upgrading calibers!
