Re: 7mm-08 vs. .338 Federal
Given what you're looking at here, I'd have to go with the 338. In dealing with the bigger game on your list, I'd just prefer the added weight and diameter that it offers over the 7mm bore size. Since you say that you're not shooting past 200m or so, the added BC and velocity of the smaller bores isn't going to offer much to you. Take the 338 and don't look back!
Did you make it down to the IWA show in Nurnberg last week? Should have been able to find whatever you were looking for there, and it was a great show.
