Best homemade for stock darts?
Posted 12 November 2013 - 01:36 PM
I just recently finished a pretty standard Rainbow with a 1-1/4" PVC plunger tube, [k26] spring, 6" of draw, and 11" CPVC barrel. I'm getting about 110 feet on elite darts with it but they are rather inaccurate and fishtail a lot. I've been told that this is a limitation of the stock darts that I'm up against. For the time being I'm not interested in making my own darts and I'd like to stick to the stock darts. I'm wondering if anyone knows of a configuration that will give me good performance but not over power the darts.
I'm considering a Rainbow Pistol with 1-1/4" plunger tube and half of a [k26] spring but I'm not really sure since I haven't tried it.
I'm also interested in what configuration folks are using for darts with larger heads, like the suction cup darts or the velcro taggers. I'm interested in making a front loader for these, probably a pistol-sized gun, and I'm wondering what kind of air volumes and barrel tightness people are using for these as well.

Probably the best way to dial back the power on your rainbow would be to make a custom barrel with some built-in inefficiencies (i.e. holes). All you need to do is drill a few very small holes in the barrel to bleed off some air volume before the dart leaves the barrel. You can do this clustered at the very end of the barrel, or use a few smaller holes at the base. Experiment....and take care to not leave any burrs in the holes.
As far as your second question, suction head darts work well in .5" sch40 PCV.

is the best you can do for stock darts, and in particular large headed (suction cup, tagger, sonic, etc) ammunition.
Streamlines and elites are unstable at high speeds, although elites remain useable at higher speeds than their predecessors. Most of the ammo with a ~5/8" head remains stable at much higher speeds than other stock darts, and thanks to greater weight and better aerodynamics, can actually outrange most felt-padded darts like slugs and AMIORS when fired in an arc.
The large head, unfortunately, makes barrels difficult. If you want a tight 3" barrel, then you can press the stem into CPVC or another tight barrel material, but this is difficult and often time consuming to reload in play and reduces range and accuracy compared to a longer barrel. It is probably your best bet if you want a sidearm / homemade nitefinder equivalent.
For a primary blaster, the benefits to range and accuracy make a long barrel preferable, and this means the materials have to fit the head, not the stem. There are not any effective tight-fitting barrels for the dart head, but there are effective loose barrels for this (1/2" EMT conduit is best, but 1/2" PVC will work). If you want much power from a loose barrel, you can't use a springer, and you are best off using a HAMP or a blowgun. The BATS feed mechanism works great with blowguns and HAMPS alike if you're looking for better refire rate or a bigger project. There are such thing as hoppers for taggers, like this:
but they don't have the reliability of conventional wye hoppers with hopper-friendly homemade ammo.
