Well I went down this path. All of the above are correct. The thing I gravitate to is availability of components. WM is gonna be king in that aspect. WM ain't loosing ground to fps to the prc hardly at all. That's been proven time and time again. The nosler will gain you a little more fps. The prc is built to reload. But if you happy with shooting up to 215's then I say stick with WM. I had at one time a 300 prc, 30 nosler and a WM. Now I have 3 WM's and no others. Same components to use. I shoot 215's in two of them at 3,020' with a 26", 2,940' in a 22" suppressed and one shoots 230's otm's at 2,920' with 26". H1000 and N570. My vote with all you have eluded to would be the WM.
