We had the once-in-a-lifetime opportunity to shoot and film a Gyrojet carbine and pistol. Sean, who owns both guns contacted me last week and we were able to set up this amazing shoot. We were able to shoot 4 rounds, we recovered 3 of them. The rounds we shot were the early-production 4-port 13mm type. Later, they used just 2 ports to save production costs.
The reputation of these being inaccurate is very true. All four rounds fired the first time - not bad for 50 year old ammo that had a reputation of being unreliable.
Even though these were shot only 30 feet, the rounds reached maximum-burn at around 3 or 4 yards and burned-out at around 6 yards (maximum velocity of around 1250 fps). The velocity at the muzzle was around 350 fps out of the carbine and 250 fps out of the pistol, which would HURT you since these 13mm rounds are around half an ounce each. So the rumor of you being able to put your finger in the barrel and stop the bullet is exaggerated.
