There have been some .30-32 pellets made, but they were pretty crude.  The ones below were some brought in with some Philippine .32 co2 rifles. (pictures has unfired/fired examples as I was testing ball fit).


On really high powered PCP versions, they are casting full weight rifle type bullets of 115-170gr. (or ore if desired).  Think a Diswcovery or 2240 type conversion would be in the league of the Philippine co2 rifle and use ball.
 


Even a ball runs about 45gr., so if you can get that up to 670fps, would earn right at 45 foot pounds.  Think that 600-675 fps area would be about all you'd get out of a Discovery without scrapping the valve and designing a new one.  the ugly co2 rifle would manage 595 on a good day (595fps with a 45gr. ball works out to  about 35 foot pounds).

The first owner did tell me he used air in it a few times, going up to 1000psi and getting 650fps.  But that thing had this massive valve (simple and crude) that moved a &^^&-load of gas.  Don't think even a modded Discovery valve is going to be able to move that kind of volume.



Forget taking the time to fine one of those Philippine riflesÖwas the most crude rifle Iíve every owned.  Was more like folk art that gunsmithing.  Had fun getting to look better, not leak, and shoot as a project, but was not something Iíd expect to last more than a few hundred shots.

Mr. Ribbonstone,
Thank you for the excelent comparative photo, and what I feel is a very accurite description
of the Philippine rifle. We had a Garco "survival rifle" in .22 with the foot stirrup pump built in the lower tube, pump a couple hundred pumps, get a few shots. Someone that was very skilled with a hack saw & welder made it and it even had galvonized roofing nails holding the butt pad on.

 Tammy had a ".380 shot pistol" 22xx from crooked Barn it used either crosman 1100 shotgun shellss or round ball. With a slightly reworked factory valve it shot 350fps when nice and warm outside.
 Sometimes larger bores make more power with the same set up as a smaller bore. The most we ever got out of the .177 Discovery was 27.8fpe (and that was with a NOT recomended overfill) and every shot dropped.
 Maybe you should get one and lets us know how it turns out, I am certain other would like to know.

Tempting me, but on a QB platform.  Could drive over to Southern Airguns in about 45 min.  Besides fully assembled rifles, it seems he has the .32 top-half as well for DIY.  Have a 3K PCP tube currently working with a .177 barrel that could be used as the bottom half.

But I still remember that .32 co2 rifle. Even when running right:
Was ungodly loud.
Needed a better back stop as it tended to chew it's way though mine.
Can't think of anything I need to shoot with that kind of power.

Found some old pixs of that co2 Philippine.
Just to give you and idea of how that co2 rifle got the power it did: Like at McDís, they supersized it.

The bolt on top if from that .32, the one on the bottom is a Benjamin. 

This is the striker and massive spring that powered the co2 rifle.

Farco shortcomings, and tehse are NOT all of them:

Things I didnít mention, but might need mentioning before anyone trys to huntup one of these guns.

The  stock was painted with fake tiger stripes. Thatís a little thing, something easily cured with a refinishing.

The end caps were not drilled on center, had no o-rings, and used a bent nail for a cross pin. Were sealed by rubber cup-plugs UNDER the end caps, but they leaked.


Did lathe o-ring races and added o-rings.  Re-drilled and tapped the cross pin holes for set screws.

The butt pad was held on with nails.

Inletting could have been done by an epileptic beaver with dull teeth.
