Great job, Bolt! Your bringing sexy back to Haven!

The code does assume a ballistic trajectory...one without swerving and spiraling, etc. You just have to choose your darts carefully. Straight stiff uniform darts will give a pretty good ballistic trajectory.

I agree about the mass. What I like doing is take a 6-32 1/4" setscrew and shoving it through the hole in the tip of a streamline into the cavity in the dark orange rubber tip. You can fit 2 in there but 1 does a world of good and doesn't add a huge amount of weight .

The gun delivers the same amount of energy to the dart regardless. So if the dart weighs more... than the muzzle velocity drops. What's interesting is seeing this when you punch the dart weights and velocities into the codes and the muzzle energy never changes. Impact energy changes though as the momentum does increase with dart mass.

Ok that makes a lot more sense. I thought you were getting some really great results on stock nerf darts. Inconceivable haha.

The observations you have are often found in Airsoft. bb weights are controlled with tight tolerances. Which is why it pays to buy the good stuff. .20g bbs dont cut thru the air as well as .25 or .28g bbs in moderately modified guns. although FPS is slower with a heavier bb, they fly farther, stabilize better in cross wind, and have similar energy upon impact. Yes they sting as much and reach farther.

So it makes sense to add weight to stabilize the darts.

Thanks Bolt.

I can honestly say I have never seen anything more beautiful, in design or application, in my entire life.

Anyways, are the ranges given using a setscrew in the dart boltsniper?

No, range is with a stock dart. Range with a weighted dart is not that much different though.

I've never seen such craftsmanship. Once again, you've outdone yourself. Seeing the FAR got me in and seeing this is pulling me back in after a long absence. Absolutely amazing work.

Magnificant! I so want one for my birthday lol! If there was a price list I missed it but how did you spend on parts?

[Daniel Beaver]

Ahhh... so that's the reason for all the natural disasters lately. Christ has returned to the earth. Good to see you back in the homemade toy gun business, you are an inspiration for us all.

Parts are one thing, but good lathes aren't cheap either. The one our robotics team uses is a nice one, but not high end by any means. It's MSRP is $1600, but G.M. donated it (Sponsors rule.).

While on the topic of the ballistics of nerf darts:

I for one have pushed a nerf dart past mach 1. The result is a shower of nerf dart confetti after about 10 feet.
This was accomplished by using a lighter than air gas, at around 2500 psi. The sound was insane.

It gun was simply a homemade QEV with 3/4'' porting, attached to a HPA tank, and a CPVC barrel.

Yeah, I wouldn't really expect a dart to survive it.

Not sure what I missed, but how are you able to launch streamlines that far without them spiraling out of control?

Black magic. Or mad skillz. Remember, sufficiently advanced tech is indistinguishable from magic

(ObConfession: I misread the original post and thought iFalcon was asking "how far". My fail.)

Hot Damn! What I missed on that month off! GREAT work!
