Wrap paper towels on paintballs or put a paper towel, then like 20 paintballs, then another paper towel so they don't roll out. Great shotgun, but kinda nasty in your barrel.

i test my seal by pouring water down the barrel and putting a few pounds on the piston so it seals and no water leaks.

earlier you asked about good ammo for 3/4 barrels, well a roll of pennys fits perfectly (sure it cost you 50c a shot but the damage is awsome)

Or drill a hole through a stack of 10 pennies and put a bolt through with a nut at each end.

Hahaha ohhh the class currency ammo... yea i like nonames ideas... slightly cheaper than the whole roll.... i also think that 1/2'' copper pipe fits perfectly into a 3/4'' PVC barrel so i may make some copper bolts...

Spray paint them bright orange and you won't lose any. And you can completely blow cinder blocks apart in one shot. :twisted:

It fits... but far from perfectly. Try 12 grams.
