what do you want to use it for?

For little stuff like groundhogs the Roberts would be my choice.

For deer it is a wash.

For larger game or some long range target work the 6.5 would be the way I go.

Rifle? For the Roberts I would be get a Kimber 84M in either Select Grade or Montana, whichever blows your hair back. I'm out of touch on the 6.5X55 but a Ruger Hawkeye or similar would be very nice. That of course would make a very fine Roberts as well!

Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!
