Bring out the chronograph/ballistics gel for the next video and shoot some groups. It would be nice to see how practical it is vs just a silly range toy.
Does it have any hope of stabilizing the bullet with such little barrel? And assuming it does group less than 20MOA, how hard does it hit?

It is a one in 10 twist, so I am currently limiting to around 200gr bullets or lighter. At this point I have not shot it for groups yet. However I have fired several rounds at a large piece of cardboard and 155gr cast, 140gr tracers and 200gr cast have all left mostly circle holes. There have been a few that were slightly out of round but not enough to where I, at this point am overly concerned.
This was not built for any real purpose other than I wanted to see if it could be done. Not really practical. I guess in theory it could make a cool PDW, but not a first choice for that.
I have a few subsonic loads that I like for reliability, but as I said still got to get them on paper. I have managed to push a super load to 1300fps using the 140gr tracer. But I think I can get it faster than that. I am hoping close to 1500fps. But only testing will tell.
