Ramset Powder Charges Drive .22 pellets at Hyper-velocities
We got some impressive results shooting .22 PELLETS out of a firearm using nail gun blanks bought at Lowes hardware. This was our second attempt at doing this. The first attempt, tried about 4 months ago resulted in failure. The first shot, the entire base of the blank blew off and most of the blast came out of the ejection port of the rifle. The rest of the case was stuck in the chamber and we did not have a cleaning rod with us to knock it out.
It seemed logical to fix the pellets right onto the ends of the blanks. However, this did not seat the pellets high enough in the chamber. I can only guess what occurred at the split-second, but I think the pellet did not transition from the chamber into the barrel smoothly, so the blast took the path of least-resistance, blowing the end of the case off right out the ejection port.
We had 100% reliability by muzzleloading the pellets so they were seated in the barrel, slightly above the chambered blank instead of directly on it. Although that is typically a bad idea to do, (short starting -look it up) it worked well in THIS application.
