Thanks very much for that information, I was expecting as much but hopeful none the less.In looking at the Anschutz 1782 it likely isn't a footprint that would be supported by and of our current inlets. It would be best to contact Anschutz directly to confirm any compatibility, but I suspect it's going to be to their stock only.
Barrel length becomes a personal preference, you might give up some speed on the top end with a 23" barrel, but it won't be the difference between shooting distance successfully. It's always a plus and minus game; go with what feels best for you.

Would have been nice to have the ACC chassis across all my rifles so I might have to rethink the Anschutz option.
