Time will tell. The wsm's were meant to end the old magnums. they didnt. In fact id say the PRC's will end the wsm's before they do the Old mags. I personally didnt overly like the 7mm rem mag when I had one. mainly feed issue based in the rifle I had. But it worked. It was never super popular unless you were after something a little extra.
I mean if I had to pick up either a 223 or a 7mm Mg, it would be the 7mm everyday.
Ive seen a couple of people lately who bought the PRC and did the choppy choppy thing and ended up disappointed with a powder burning 7x57.
Its going to depend on if you reload or not to get the best out of these things.
