It would be nice if Clymer provided headspace gages to BRITISH MILITARY SPECS instead of SAMMI specs.

What are the odds that you would find a .303 rifle set up to SAMMI specifications rather than Britishicon? How many current sporting rifles are made in .303???????

As far as I am concerned, SAMMI gages are a waste of time in .303 and the person who was thinking 30-40 Kragicon rim thickness is the same as British .303
must have been smoking funny cigarettes!
