Personally I bow hunt during archery season, and when general season comes around I use my rifle. In the end, it is all about meat. Frankly, I'd go with the .308 over the 06 since you seem to be in rather right places, the shorter action may suit you better. throw some good 150 grain bullets behind it and you are ready to rock. Winchester Powermax bullets are easily some of the best I've used and seen especially for the price. But if you wanted to splurge, there are other options out there. As far as broadheads go for archery, G5 Motecs seem to be the most popular and likely for a good reason, but I suppose that most of them do about the same thing. the tricky ones are the mechanicals if you want something fancy.
