I use Wilson Cartridge Case gages to set my resizing die, if I am loading for two or more rifles of the same caliber I drop the fired cases into the gage (has steps in the gage to show minimum and max heaspace) to determine which rifle has the least headspace. The rifle that has the least headspace is where the sizing die is set - .001, if the resized cases function thru the least headspace chamber they will be fine for the second rifle. Using the Wilson Cartridge case gage you can set your sizing die precisely so your finished ammo will function thru multiple chambers, follow the instructions and you will be fine. Hope this helps!
