I just converted my 300 RUM to a 338 Edge, burned the barrel out. And am currently having a 6.5x47/6.5x284 Norma built on a predator action, mcmillan stock, jewell trigger, broughton barrels. I have shot both the big guns and the small guns. I am 240#'s and have no problems with recoil, but I do have a problem with muzzlebrakes and how loud they are. Magnums get hot faster than small calibers, so you can't shoot as much, magnums will burn barrels out faster, they cost a lot more to reload. I went with a heavier gun that won't recoil as much, 6.5x47 can take 2000+ rounds down the tube, 6.5x284 will drop elk out to 1000 yards. 338 Edge will produce the same energy at 2000 as a 7mm will at 1000, but it's overkill. Accuracy is what matters the most.
