		<description><![CDATA[I built a tactical laser - 186,000 miles/second muzzle velocity; beat that!  (;-D

Seriously, however, what is the twist rate?  At a nominal 12&quot;, that&#039;s 300,000 RPM - getting mighty close to disintegration speeds.  Seems like you&#039;d need permission from Starfleet Command to fire that.  When a .22 
bullet disintegrates at that RPM, the tangential velocity of the fragments is about 3,500 f/s - enough to cause damage orthogonal to the bullet path over quite a lateral distance.  Not safe to shoot if so.]]></description>

Wow! What kind of twist rate are you running for a 224 going that fast? Have you had any trouble with bullets tumbling or keyholing targets? I would imagine if the bullet spun too fast it would spin the jacket right off.&quot;

It&#039;s not too difficult to find bullets that will come apart when driven to too high an RPM.  I have done it with .224 bullets (these were factory-labeled with velocity warnings and performed as they should). I&#039;ve also had it occur with lighter-weight bullets fired through a Swedish Mauser. (which generally have a relatively quick twist rate.) Anyway, the concentricity and tensile strength of a bullet is not something that can be ignored.]]></description>
