SNAP Carbine, breechloading with attached underbarrel absolver shotgun. The absolver is powered by a Big Salvo tank.

I will also point out a possibility, as my panther could easily pull 20+ pumps. I'm gonna start a conspiracy theory. I think buzz bee knows what people did with the panther, and that the same thing will happen to this gun, the have purposely put some sort of "auto fire" mechanism inside the valve, so people don't make stupid crazy stuff ( like what could be done with a titan. On the upside, it means no tank over pressure explosions.

Assuming it utilizes some type of piloted air valve, in which the trigger releases a small amount of air to actuate the valve, it could be entirely possible that the small trigger valve can't take the higher pressures and simply leaks at a certain point, actuating the main valve in the process.

Oh totally! I used Autodesk Inventor beforehand, but my school changed program licenses around so now I got free Solidworks to do it all up in. Pretty neat stuff, much faster than measuring out with rulers and such, and fantastic for visualizing it all.

Sounds nice. In the post directly prior to yours, I linked to an earlier blog post of mine where I summarized the available drag data: http://btrettel.nerf...com/archives/78

Based on tests done by Daniel Beaver and koree, I would suggest using a value of 0.67 for the drag coefficient. This value fits my flat-fire (small angle) approximate theory very well and is in concordance with wind tunnel tests done for circular cylinders with flat and smooth noses.

You can read more about the flat-fire theory in my old notes: http://trettel.org/p...stics-notes.pdf

Oh thank you! Sorry I missed that. I'll see what I can do about that range table, though it'll need to be proofread in real testing.

If you haven't, calculate the approximate drag force of a micro dart in terms of velocity (in ft/s for use with chronographs) and mass (in grams).

This way, we can use the drag force and gravity to create another formula to get an approximate range from Chronograph readings. This would only work for accurate darts, though. So not for streamlines.

I think the best way to find the drag coefficient would be to drop a dart with the same reference area as a standard slug dart with known mass and from a known height. Timing the drop should get a proper coefficient (If I understand it correctly).

Hmmm. I was writing a ballistics program to calculate ranges at different angles and such. If I had a decent value on the drag coefficient of various NERF darts I could make a few tables/graphs for reference.
