Why make non-lethal 3D printed 9mm bullets? Well, why not? The bounds of 3D printers are being pushed all the time, and firearm enthusiasts love finding more applications for this form of manufacturing.
This video actually came from a reader of The Firearm Blog who shared the video on Youtube. It wasn’t exactly a scientific test, but it might be interesting to some of you nonetheless.
Here is what The Firearm Blog had to say about it:
The bullets were printed with PLA, a bio-plastic made from corn starch in the USA or sugar cane elsewhere in the world. PLA is commonly used in 3D printers as an alternative to ABS plastic (think lego bricks). It is easier to print (at least in my experience) than ABS requiring lower temperatures and it has a pleasant non-toxic smell.
The bullets printed weigh just 13 grain, about 10% of the weight of a regular 9mm bullet. This puts them in a “less lethal” category along with rubber bullets. The subsonic variant of this round (loaded with 1 grain of N320 powder) would have had under 31 ft/lbs of muzzle energy, less than a third of a .22 LR round. Still, I am sure it would sure hurt like crazy if one of these hit someone in the chest.
A supersonic load had the same 13 gr bullet but backed with 3.8 grain of N320. The velocity was not tested, nor was the accuracy.
NASA is warning that we have 13 months to get ready. See why FEMA has ordered 300 million body bags in the face of what some are calling WWIII. CLICK HERE (sponsored)
