Well yeah, rifling on normal paint = useless.
Rifling on First Strike (even though they already have kind of rifled fins to stabilize them) work amazing. They weren't designed with rifled barrels in mind. Its just a happy accident I guess.
I'll post it again (its in the original post). Ive even started the video at the correct spot lol. First, you'll see a grouping of First Strike through a normal smoothbore barrel at 135 feed. Much better than normal paint (which he shows right before this if you want to rewind a bit), but could be better. Then he throws on a lapco rifled first strike barrel (which is a TERRIBLE barrel btw) and watch how tight the grouping gets. A better barrel would get even tighter results.
And yes they ARE spinning. The fins are SPIRALED. Basically after tests it was discovered that in a smooth bore barrel, first strikes won't spin until AFTER they exit the barrel and catch the wind essentially. The rifled barrel pre spins them so to speak. Which tightens up accuracy as they aren't "winding up" mid flight and wobbling off course. Thats why there is such a drastic difference between the rifled and smootbore barrel grouping.
And furthermore, the macyworks shaped projectile pictured above in the original post has NO fins as you can see. That compression band in the middle helps it grip the riffling in the barrels for maximum spin.
