paintball sniper

alright heres a new idea i just thought of that takes care of a major issue with this design: the fact that the paint inside the ball would not spin, causing instability. so what if you cut open a paintball at the seam and put some sort of barrier in between the two halves of the ball. something like latex or thin plastic like in bags. this would separate the sphere into two non-circular sections, therefore the paint could not help but move with the shell because the barrier would be attached to the shell. with this modification i see no reason why this "paintball" would not act much like a real bullet. i just drew this in paint:

Yoru forgetting that the paint still moves when it will spin.  Momentim is your enemy, the paint moves, and keeps moveing, the spins become more and more exagerated.  Then you are forgetting the fact that latex is not biodegradable, you are left with many many bits of latex all over.

I see you all are arguing and I don't care for any part of that. I have shot high power rifles for a while and have a good understanding of ballistics and thought I might give some input as far as comparing a paintball to a real rifle bullet.

For your barrel you might as well go with a 36" if you want to test 30". If you have the ability to machine, build a prototype. Find a 1/2">3/4" ID metal pipe, plum it up and drill it out to .68, and then polish the crap out of the bore. No easy tasks to make a straight and smooth barrel, much less spiral groove it.

The problem with getting your accurate flat shooting far-reaching paintball doesn't matter if you can get it rotating or not. (And yes, the shell would rotate and the paint would hold still)

The paintball has way to high of a drag coefficient because how wide it is. Most projectiles that are .50cal or wider are coming out of the muzzle at >2500fps to get to their distances, they are as wide and heavy as they are for energy. A paintball would get ripped apart from it's own wind resistance. 

If you know basic physics you understand that the only way your projectile is going to go further is if it is going faster, unless it is acted on by another force to give it lift (flatline backspin). Hold your marker level and get a stopwatch. No matter what you set your velocity to the ball is going to hit the ground at the same time. Gravity is constant (-9.8m/sec squared). The faster your ball is going the farther it will go, but it is always in the air the same amount of time.

But we all in paintball have a 300fps limit, so you need a slim (drag coefficient) and fast (distance), safe paintball (make it light). A standard load of.45ACP comes out of a 4" barrel at around a slow 880 fps to give you some relation, it is a very slow pistol bullet, but very heavy. I wonder what breaking the sound barrier would do to a paintball? They are too fragile to go faster then they already do, but if any more dense they would be unsafe. You need a frangible substance that disperses better then paint.

I think of accuracy with paintball guns like I would a smooth bore black powder gun. The dynamics are more similar then a rifled barrel.

What you want for accuracy is straight and smoothness, no friction.

As far as the scope, why? I know that the sight radius is short on a paint gun (I took my sight off and look down the barrel). If you cannot hit a pie pan @ 100 yards with iron sights then you don't deserve a scope, and you are definitely not going to be faster with it. I would put a good front sight on the tip of your barrel if amiability were paramount. It is at least a smaller target to have on your marker.

Must be bed time.

Hehe, thank you very much

Simunitions, they still exist.  They are by no means safe.  One guy was killed because he didnt wear his neckguard once

Heres my opinion: Try it, do a mock up of your idea with what you've got. There is no better way to find out if something works than to test it. If it doesn't work, move on and keep thinking of a way to reach your goal. You will never get anywhere by saying "oh it won't work" and then giving up. Hell, where would the Wright brothers have gotten with that mentality. 

My main question is this.

When you put the lightweight material to the back of the ball, it would have to be sturdy enough to grip the firling. Paintballs dont have enough weight to them to be able to offset the weight of this sabot that we've put on. At the velocity that you'd be shooting, there wouldnt be enough power to keep the heavier sabot from falling, dragging the shot down with it.

Thats what happens when you post half asleep

ya and is @$$ of buddy shot him in the neck thats y!!!

they are safe i was in the can.force and i trained with Simunitions so let it go!!

Y do you think you know every thing the guy has a good point about the sniper round instead of making it of Styrofoam you make some flaps of the same stuff the ball is made of....... i guess (tought from the top of my head so its not the best)

Oh and before you tell people to learn ballistics you should finish kindergarden........you know to give you a bit of credibility!!
