Unbelievable. I bet most seasoned reloaders could actually produce them.
I watched it. It was good. I don't think they'd be that difficult to make honestly. When I first saw the video I thought to my self of how I would go about making them and no lie thought they would go about 600fps. You would need a cartridge with a slight taper like 300BLK. I bet a 7.62x25 could also work even though that's an actual shoulder. Then you would need a plug of pretty tight tolerance made of a material strong enough to withstand the blast and create a good seal but not add significant weight to the bullet weight. You would also have to load the charge and the plug before forming the neck. Then you would need a heavy for caliber bullet. One long enough that it could make contact with the plug. With 300 BLK its obviously easy to find a bullet suited for the task. I've seen the tokarev loaded all the way up to 115 grains (still supersonic). If the 115 could make contact with the plug then it would just be a matter playing around with charge weights. You could of course go heavier than 115 and the higher you go the slower the fps. I think it would be a fun project. Too bad it's NFA
