[QUOTE="338Shooter, post: 2381297, member: 3449"] At 1000 feet per second, the barrel time on a 24" barrel would be .002s. 12ga bore of .729 and a 9mm bullet diameter of .355. Assuming it is directly centered in the 12ga bore you'd have 0.187" of space between the shotgun barrel wall and the 9mm bullet. Dividing .187 by .002 gives you 93.5 in/s (7.79 f/s) velocity of the shotgun barrel in a direction perpendicular to the bullet's travel for the entire .002 second flight time. If you consider it from a standing start, you'll already be behind due to the barrel requiring an acceleration. I don't think it is possible with any of the caliber for the barrel to accelerate fast enough for the bullet to touch the inside of the bore. [/QUOTE]
