When i fire my gun, Pneumatic pumped at about 70-120 psi..With a rifled barrel, When i shoot a potato out of it, It goes CRAZY, It ill go in any direction. Could it have somthing to do with sloppy rifling? Or rifling at all? If i could get this to go streight, Then itll go a long ways, Maybe....
Its a 3/4" pvc pipe incase that helps
Potato problem - Is this suppose to happen?
I would say sloppy rifling personally. Don't have much experience in this domain, but without rifling one tends to achieve a more linear path, if you can try to replace the barrel without changing much about the ammo, see if you get any sort of change from that. The pressure shouldn't have much of an effect unless your spuds are exiting at very low velocity.

This could be due to sloppy rifling, did you use the old dowel and nail system or was it done profesionally? Also, do you muzzle load the potato, because breach loading is a must. There could be a variety of different problems, rifling too tight, rifling too deep, etc... So we'll need pictures for a better understanding
I love lamp

I would go with smoothbore and drag-stabilized projectiles like darts (or even Dum-Dum lollipops, with that 3/4" barrel).
Rifling needs to be done right or not at all, or, as has been pointed out, the projectile will gain too much spin.
