I'm rolling an example of both rounds back and forth across the desk,......with a pair of very good calipers,....
Q. Is the "adapter / insert" tapered to paper thin dimensions at the cartridge base area ?
GTC
not only that , but the 308 has a bigger shoulder than 06 and less taper thru the body , for instance , you can't rechamber a 308 barrel to 06 without setting back the barrel threads .
I wanna see one of those thousands of adapters the army had , and see it work .
