6mm INTERNATIONAL (WALKER VERSION)

American wildcatters began fiddling with the 6mm’s after WW2. This is one of several versions that exist of these experiments and were popular with Bench Rest shooters. Based on the 250 Savage necked down, but differs from the Donaldson version as it retains the original length buth with a longer neck and the body taper the same as the original 250 Savage
