7wsm has been setting and resetting some of the mile long shooting matches. I've talked to the driver a few times a year ago and he had nothing but praise for the accuracy of the round and being 7mm the projectiles have a high bc.
That doesn't mean it'll hang on though. But its a good start. And has none of those magnum mystery shots we encounter in matches using magnum belted rounds. Those ones that fly out of the group for no apparent reason.

James-- wouldn't that be 22-like 62 caliber or so? They sure had some much larger rounds than 50 caliber years back.
