Is there a difference, other than the obvious, between headspace gauges for specific calibers and the family of cartridges based on the same case? Specifically I'm looking at putting a new barrel on a Savage 110. There are headspace guages specifically for the .358 Winchester, which is the intended caliber, and there are guages that cover .243,.260,7-08,308, and the 358. The multi-caliber guages are actully less expensive than the single caliber units, but that could be chocked up to the larger quantity of multi-caliber sets that the company produces. These guages are made by Forster in both the "go" and "no-go" types. Any input on this will be greatly appreciated.
