I agree with Builder. As far as I'm concerned Deep Curls and/or XTP's are all anyone needs for whitetails out to 200 yards. Shoot the buck-a-bullet models if you want to throw that kind of cash down range. But I won't do it.
Lots of guys shoot range sessions with the cheaper models and use the premiums for hunting. That's fine. But I consider it more of a feel good/confidence thing than a real need. I feel good and am confident with my Deep Curls (and my .54 lead balls out to 100 yards).
