Thanks for the input everyone.
I figured to update you on the performance aspect of the Roadblocker and it's "jumbo" sized darts.
As for 'piercing' cardboard, that really wasn't the prime intention, although at ranges from danger close to about 30 feet, you get some pretty good penetration in common corrugated cardboard (typical brown box). Rather, I figured these to be more like a shotgun rifled slug, which is exactly what it sounds like (for those unfamiliar with firearms, primarily shotguns).
It's just a big ol' bullet. The increased mass would give a much more irritating thump when shot at someone behind a cardboard/ styrofoam/ wood barricade. And yes, it stings a little when you get hit.
A bit bigger welt, too.
Ranges are NOT quite 100 feet with the larger darts, anything beyond 70 feet or so has to be arched for some increased range. Again, this wasn't meant to be a $niper rifle or any long-range shot, although a simple change to a brass barrel and micros would easily make this a fine sharpshooter weapon. It was meant more as a close range counter to anyone who cares to try a 'tank', or have 'armor', to bump and thump them.
DTReaper, I hope that answers your question. It won't 'blow up' cardboard or punch grapefruit sized holes at 20 feet (would be pretty neat though, if it could). It'll shoot through at those ranges, but diminsh quickly because of the great surface area up front.
Falcon, if I had to one-on-one with you and your PJ, you'd bet I'd swap out for a brass/PVC barrel and some of my micro stefans that didn't revert back to their hot dog shapes. Either that or I'd have to resort to my ancient Chinese Wang-Fu-Sheng-Shao-Lin monk techniques of disappearing and reappearing within range...which would be much harder since my arthritis would kick in at the worst possible time.
davidbowie...jellybeans?! Here in Hawaii we have ants with an extreme hankering for sweets, and they would be all over the darts the moment they hit ground. I use .177 caliber lead balls (like bbs but lead...old stuff), or BB sized fishing weights. They allow some adjustment if you bias them properly in the hole you bore in the front of the darts. Only downfall is that during the gluing process, air can get trapped and bubble somewhat, making the dart fronts a bit ugly. Which is okay by me since they weren't meant to be pretty when they hit someone.
But yeah, I'm pretty happy to have brought the 'ol 5k out from the 'idle' bin and make it an active part of the arsenal; I'm going to be rooting through the blasters I've not fooled with in awhile, and working on them. The RSCB 2k is almost done, the EX-3 NiteFinder is being detailed after paint, and the howitzer just needs to be glued up, painted, then mounted to the trailer, and I'll be pretty much ready for another batch of projects.
That is, when my busy working (RealLife) schedule would let me move on them.
