Hey all, so I've been interested in realizing a personal project of mine, which is to make a marker that doesn't use gelatin capsules, but a more rigid type outer shell. This would permit me to use a cylindrical, more aerodynamic shell, mags with a reasonable amount of pressure on their springs, and to take advantage of the benefits of rifled barrels.

In keeping with the low toxicity of paintballs, I was thinking of a powdered sugar fill, and a compressed and glazed shell. I think it would be nice for cloud effects when you hit concrete, and I've tried shooting little packets of the sugar with a slingshot which do leave a nice mark, but the mechanism would definitely need to be good enough to still keep working after a powder break (AK inspired?), or easy to clean.

I'm also thinking .50 Cal, and depending on the weight it could have a higher speed in keeping with the energy impact standards for paintball, plus the rifling should help a lot. Any thoughts, comments, suggestions, or trials would be much appreciated

Good luck?

Rifling still won't work as you have a liquid center. That is what prevents rifling from working.

One word: Simunition

I guess I'd have to pack the powdered sugar in the center pretty tight then, but not enough to compress it into a crystalline structure. Also, since the inside won't be glazed, there should be enough friction in there to keep the mass from slipping.

I was thinking that with the rounds I could make a mold, pack it with the material and flash heat it to get a hard outer shell. I'd have to do some testing to find out the ideal temperature and heating times so that I end up with a round that will break with the appropriately safe amount of force, but will resist normal handling.

Anyway, if anybody's got their own ideas I'm all ears. I can afford this project as long as the costs don't get severely out of hand, and I'm planning on making more than just 1 marker, of course, and to be able to produce my own ammo.

I was gonna post this yesterday as it was but today I got a new idea. How about a thin sheet of some biodegradable material that you slip in between the molds, then you heat it so it's embeded, and depending on the material you could have an excess on either side that you can wrap around the whole thing to add smoothness to the outside, or simply have what you need and then glaze the outside separately, but it'd be one way to definitely force the insides to rotate with the rest of the round.

E: Also, I want a caseless alternative to simunition, and also to try to drive the costs down. If I can make my own ammo using supermarket bought stuff, then I think that's a step in the right direction. Though I will investigate how their rounds work, maybe the process of making their ammo is simpler.

If what you have is a solid material for the fill and something that will accept the riffling you would be good. The only problem you will have is that in order to get the rifling to work on say, the glazed sugar, the outer surface will have to be glazed pretty thick for the round not to burt in the barrel.

One of the biggest issues you will have is to obtain a velocity high enough versus a thick enough shell to obtain a rotation of a round. If the shell is to thick, it will not break on a target. To thin, a barrel break. You are best trying the Rap4 (I think that is who makes them) powder round. They have dimples which will hinder and rotation, but you might be able to use them. I would suggest trying those.

Another idea is to make something like a first strike round with a magazine. A round that has a hard shell on one section that will be able to be rifled and a soft/brittle front that will break on a target

tl;dr

Find solid rounds and try them in a rifled barrel. Rap4 or pepper balls.

That's true! So gel capsules would work with a solid fill... how about I take some of those .50 cal paintballs, cut them in half and use any material for the cylindrical part of the round, adhere each semi circle on the tips (so that the back has some resistance to the pressure), and try it out.
