I ordered a set of PTG gauges from Grizzly, and they are marked "308 Palma 1995" on them. I was under the impression that a 308 go or no go gauge was a 308 gauge, But these are marked specifically for the 95 palma... Are they different in any way? what's the deal?

Are they marked 1.630 for the go gauge and 1.634 for the no go? If so I would say they are good to go, but you might want to call PTG to make sure.

Well, that's the interesting thing... They aren't marked with any dimensional info at all. Just 308 Palma 1995.... Guess I should call Dave and get to the bottom of it.
