Yeah, should probaly have a longer barreled gun, in a gun vise and some kind of optics. But you have done a free hand test with a handgun now. I will be interested in seeing the results of future testing. Has anyone ever tried a kind of rifling in a barrel?? Would it even work?? you need some spin, but too much wouldn't work too well I suspect. The old flintlocks would be the comparison in some regard, but they were single shot with a wadding to prevent the gasses from passing the ball. Don't know if it relates in that aspect , but the BB bouncing around inside the barrel is the same, and it was solved with the advent of rifling. I would think that that would be a solution, if it worked with BBs, but I will leave that to you experts to discover. I am only a theorist. hahaha

Rifled, but only works in guns that are 330 fps or under. Any more than 330 and the effects of the Hop Twist barrel are no longer present and act as a regular barrel.

Mmmmm really interesting thread!
I'm looking for a 650mm for my A&K SR-25... I was looking at the DB Custom 6.01 but right now I'm not sure... I guess the Prometheus 6.03 will do the same job. LoL!

Thanks, I will look at that. Very interesting indeed. I wonder why it is ineffective over 330fps. Experts.. why is that?? Anyone have any reallife experience with these barrels to share?

Illusion has tested it. Not sure where the thread is, maybe in Upgrades? Do a search.

no experience, but i can answer your question. the barrel isn't rifled in the traditional sense. The BB and the rifling do not touch. The rifling is used as air passages to create a balance of air pressure around the BB. Think of it as the BB being in the middle of a tornado. Now the catch is, using a heavier BB will not change this. I.e. if you think you can outsmart it by dropping fps via bb weight you will still get bad results because the AIR AROUND the bb is still over the 330fps limit. Now apparently they still perform "ok" over 330fps. A good friend of mine said these barrels in the defined parameters are good up to about 30 yards (but not decisively better than a TB barrel) or some relatively short distance. After that, the BBs literally loose all accuracy and predicability. Hence why many favor these barrels in pistols over rifles. i will just stick with TB.

yeah read some of the reviews and test results, very interesting stuff. What about a real rifling though, has anyone tried that?? would there be enough energy to push the round through the rifling? Having the rifling imparting the spin, more so than the hop up? Would the hop up be redundant? Or would you still need a hop up? I am thinking there isn't enough energy to do this like a conventional bullet. And I think that your rounds would curve from side spin. All in all, a very interesting topic.

Nope definitely not enough energy to use actual rifling. The BB would just stop.

as I thought. Not enough energy. I should do an experiment, and see what kind of numbers I can get from a launch monitor that they use for golf. I have a buddy that manages a shop that has one. I wonder if I could get a reading from a BB??? sidespin rpm, backspin rpm, etc. Might be interesting.

In conclusion, get the 6.03mm
