man I want to try a desert eagle .50 its gotta be crazy.
anyways you could try my cartridge method I'll release the details after the contest, with 3/4" cartridges you can use sanded off rim 12G shells as sabots!!!

Definitely go with a metal barrel and a full stock. If nothin more, it will look cool.

Pneumatic spud guns can reach the speed of sound, so I imagine it should be very possible to reach the 1000 to 1350FPS that a shotshell will fire at.


I have never skeeet shot before. Sure I target practice allot with smaller arms. (Ruger 10/22 + brick of .22 + a few toilets down range = 1 fun day !)

But I can only imagine you have to have some sort of shell to prevent the BB's from spreading to far apart to ht the clay target with any effectiveness (see GoatHunter and Pete Z. Above). But thanks for the help.

Ok this may be a little late but here’s my two cents ($0.02):

First, if you’re going to make a scattergun (I use the term lightly) and expect any form of performance that even vaguely resembles a powder burner you must choke it. Other wise, no matter what you do, you ain’t going to get a usable pattern.

Now to get the velocities required to break the skeet you’re going to have to shoot a light load, maybe a half to three-quarters of an ounce for a 12GA (.75cal, ¾ inch pipe).
This means less lead/steel going down range, which in turn means you’ll need a tighter choke.

Co2 or high pressure compressed air, whether from a scuba tank or shock pump, is a must in order to achieve the higher velocities required.

A piston valve or QEV are going to be necessary, but that’s a given as they’re the only thing’s that will take the required pressure and still work efficiently enough.

You might want to consider a double gun, seeing as how you’re new at skeet and shooting an air arm, a follow up shot is going to be nice.

Other than that there’s no reason that a pneumatic shotgun could not be made that would be usable for skeet. The hardest part being choking it, that and learning to shoot it.

But that’s just my two cents.

can you adapt a choke tube for use on it?

You'll get many a strange look if you show up at a skeet shoot with a spud gun :? I'd check with the range owners before attempting such a stunt.

I think you'd have to go for bigger-is-better pneumatic, 2-3" barrel as long as you can make it, a fast acting valve (exhaust valve piston is your best bet) and as large a chamber and high a pressure as you can go.

Load up a sabot and BBs, and forget aiming, yóu'll have to go for the punt gun effect :D

Judgment_Arms -- its not too late. I am not skeeting for another 3 weeks after finals. So no probs there.

JMR-- I will go there first to see the place to make sure its cool with the owner. Cant imagine they will mid though. Others are using 12g shotguns!

Thank you all for the feedback.

are you suggesting that a lighter projectile should be used to increase damage? :? cause clearly while lighter rounds are faster they are not stronger due to less momentum.
also how well would a BBMG do for skeet :D if that's not what you meant then that might have made me look dumber

i think that Big 5 has some of those skeet targets for those high powered pellet guns. they would break easier that the ones for shot guns, but im not sure.

No Iknowmy3tables, what I mean is, by having less shot to a round (load fewer BBs) each piece of shot will have a higher muzzle velocity, meaning more impact down range.

And no a BBMG would not have the range.

Here, I believe that something like this might work:

If you get .177cal [u]lead[/u] BBs you’ll have the oomph to take out the bird at about 30yards.
