Swapping Scopes

Do any of you swap scopes between guns? Do you rezero between each use or just use "0" marks for the one you use the most and then just start at a different hash mark with a dope chart for the other gun?

Not exactly sure how to word what im saying. I know during my rifle build the maker said that he would going to use his scope for sight in.

I always re-zero unless I use one temporally for just load development.

Gotta re-zero. Starting off your 0 dope at anything other than zero is a recipe for a miss.

The Viper PST will be pulled off the 7 Rem Mag maybe next week and put on the 7mm-08. Bore sight it once its moved over, then zero it on 100 yard paper. I will document what it took to move from 7 Rem Mag to 7mm-08 (elevation and windage turret adjustments). So the next time I can do it nearly without shooting it. But I will verify anyway. Once it moves to a new rifle I will zero out the turrets.

I've never checked to see just how close to zero a scope would be when moved from one rifle to another. I've jockeyed scopes around quite a bit though and I don't recall ever being surprised at how little adjustment any of them needed during boresighting. Don't really know, though.
