My neighborhoods has a 240 Gibbs. I know he doesn't have any ammo for it
If your Model 70 is a long-action, you can do anything you want. I had a 25-06 years ago, and liked it. Have you looked into a 25-06 Ackley Improved? (I'm biased--I'm shooting a wildcat .20, and waiting for a 6mmX6.8SPC barrel.)
