ABSTRACT
Ammunition and rearms are broad, diverse, and dynamic topics. New products are regularly introduced to the marketplace; new companies appear on the landscape; and there is constant change. In addition, the uncommon, rarely seen older example comes out of the woodwork, occasionally challenging even the most knowledgeable person in the eld so that, in eect, the students of these subjects must look in both directions to where the industry is at the moment and what has already transpired to round o their knowledge. Inevitably, the examiners who claim to have seen it all are taken to task when that which they did not know suddenly appears aer they already thought they knew it all.
