Demonstration of function and early-development velocity of the Dagger in a carbine (16") barrel. As of posting, our present prototypes are about 75fps faster in a pistol, so we can expect over 2700fps from this carbine with the most current revision and even more in the future. Bullet weight of these old prototypes was 49.5gr. and pressure about 40.5ksi (now 42ksi).
From this test, we know nose angle needs to be decreased from 25deg to 24deg to reduce wave drag, according to the associated Mach angle.
