and.. improvements of 50% mean the HomemadeDarts
Because HomemadeDarts Low accuracy
With all due respect, I don't have the time, patience, or money to test every claim like this. You're the one making the claim. Back your claim up with the test data you would have to take to make the claim.
Edit: I've been told that 3DBBQ's darts are unweighted. This would allow rifling to improve stability and in turn improve accuracy, so the claims are believable. My points below about improving the weight distribution such that the dart's center of gravity is in the front of the dart and increasing muzzle velocity and dart inertia still stand. Rifling is pointless when the weight distribution is good.
The two easiest ways to increase accuracy for Nerf darts are to increase the muzzle velocity and the dart inertia (mass). Safety concerns prevent these two from increasing too much. There is a practical limit to accuracy. Until a gun and dart combination reach that limit, I see no reason to futz with things that probably won't do anything.
Rifling to improve accuracy seems to be one of the "holy grails" of Nerf and it will remain so because it can't work. At best it would improve a dart's stability, which typically is already excellent due to the weight distribution as I've mentioned. At worst it will reduce stability, tear the dart, and contribute to leaks.
