Yea, I'd rather go with a 260 rem w/120gr & 140gr, 308 win w/180gr and a 338-08 w/225gr. All with H4350 powder. Three of the most inherently accurate rounds developed and with plenty of punch.
The 6.5-06, 30-06 and 338-06 would accomplish the same.
I put those in to add some of the metrics but, they are some affective rounds and do make a great combination.
Bring them in on a string. I love this term, if you want to be successful on calling in Elk, try not to just sound like the other caller. We all laugh at each other when we are practicing Elk calling at home or while camping. When I first started calling in Elk, I had no idea what i was doing and it's funny how many I could call in. The biggest Bull that I have called in to date was actually my first. I was making cow calls and screwing it up big time. But it's obvious I didn't screw up...
