Q: It seems to me that I read somewhere that you guys use a cone-shaped breech. Why is that?
    —C. Jacobson

A: That's correct. We do countersink the face of the breechplug into a coned configuration. This provides a number of advantages.

First, the fire from the cap flashes into the powder charge at the point of the cone. This eliminates the possibility of the "burn" choosing any number of random burning patterns as can happen when you simply spray the cap flash into the side of the charge. The flash always begins at the point of the cone and works its way forward through the charge. This consistency of ignition translates into accuracy.

Second. You ex-military men probably have heard of the shaped charge principle. Well, the coned breech provides us with the advantage of the shaped charge principle and amplifies the ignition impulse and energy release. It's part of the reason why the Zephyr's barrel can completely burn powder charges of 200 - 300 grains.
