My buddy wants to put a long range 7mm elk rifle together, and I'm thinking since its a custom then why not build a 7 wsm on a model 700 long action and avoid dealing with belted magnums. Hornady is making 7 wsm brass now and it's getting good reviews so that's a plus. I've got a 7x300 wsm and it's the most accurate rifle I've ever shot (1/4 moa @ 200 yards). If you were looking for the best accuracy, and ease of loading which would you choose.. 7 wsm or 7 rem mag? 180 grain bullets will be used, and the barrel will be throated appropriately..
