Muzzle velocity is going to be 250 ft/s.

And jsefcik- i said a reusable instant stick epoxy. JB Weld would never work. Please read the thread before posting.

Knowing what the target it is would be a lot more helpful, as well as knowing if it can be "harmed" or not.

Target will be mostly just walls and big backstops- flat surfaces, not fragile. I want the adhesive to be on the front f the round and stick the round to the target, keeping it straight out. Projectile weight estimate is 2 oz MAX (probably around 1.5), 1.5" barrel, round approximately 2 inches long. and then the round has to be able to be removed, so no permanent sticking. Preferably no damage left to target

Some kind of clay or wax sounds like the best solution, possibly with a thin frangible cap to keep it together during launch and flight. Something like the plastic eggs in which kinder surprise toys come in.



I made an airsoft BB stick to steel once

I was thinking about those eggs, not sure if they'd break or not however... Given the fairly low velocity.

Wax seems like a good option, only wax I've had experience with is paraffin and that wouldn't work.

I wonder if there is some sort of gel out there that would do it, as that would be ideal.

EDIT: my roommate has this stuff for hanging posters that's extremely tacky and vaguely resembles bubble gum in consistency, but stickier.. I may have to experiment with that and see if it could be up to it.

I'm sure they will, they break if you throw them at the ground hard enough, even if they're empty.

I bet candle wax would work well, especially if the launcher was a combustion and it got warmed during firing

This stuff? It would probably work too if suitable contained.

Yep that stuff.. I'll have to see.

And JSR just so happens to be a combustion, modeled after a grenade launcher. 10" chamber, 12" barrel

I would try kinder egg full of candle wax first, definitely cheaper to start off with.

This brace wax stuff will stick to walls with out to much trouble.

that or some wax from a toilet wax ring


or some of this...



or some tar would also probably work now that I am thinking about it, though it may be too messy...

Yes after you let it dry

HMMMMMMMMMMMMMMM, what about silly putty?? That may have some potential!!

I dont think silly putty would work, from what I heard, if it experiences sudden impact, it will shatter.

I don't reccomend tar, unless you're ready to dispose of all the equipment involved in the shaping. You can get tar as a driveway sealant, it comes in a cord with a plastic wrapper on it (because it really IS that sticky) that is to be melted along with the tar.

Beeswax also won't do, but isn't entirely out of the question. I dip beeswax candles in the winter (great excuse to perfume and warm up the house), and buy large chunks of beeswax. Just hitting the block with a hammer breaks it up into sharp chunks, and rarely leaves enough residue on a nearby surface to be noticeable. However... if you melt it and mix in some oil, you could have something that's exactly what you're looking for. It's easy to clean off too.

I used to shoot the wax that's wrapped around babybel cheese out of my slingshot at walls with pretty good success.

edit: saefroch wouldnt tar wrapped in a plastic wrapper be perfect? its like a ready round because that would stop it from sticking to your barrel but it would spread out and stick on impact
