What range will he likely be shooting at? The 243 isn't known for its range. And aren't those northern deer on the large size? Sure, the 243 has taken lots of deer, but I think the real question is whether its the most appropriate tool in your particular area. I'm with you on the 7mm-08 but he's probably stuck with what he bought at this point.

The super short magnums pretty much hit the market with a thud and haven't found the user acceptance that the WSM line did. If that doesn't change he's likely to need a reloading kit before too long. Even the folks over on the short mag forum seem to have written them off.
