These FREE pool water tesster bottles work PERFECTLY in 2" chambers. These are from Pinch-A-Penny so if you know of one where you live, just ask 'em for a free water tester bottle!! Works great if you fill it with water too.
Any kind of caulk gun tubes work great in 2" barrels! I picked these up at a construction site
Wine bottles are AWESOME!! Just gotta find the right bottle for your gun. I use these in the 3" barrel. Just put a little tape (clear packing tape is best, less friction) on the end and let 'er rip! Fill em up with water too, very cool. They also can be used over and over again of they don't break, but don't worry, they are stong!
Water works great in pnuematic guns. Just be sure not to fill it up all the way. Use a few cups .
Golf balls are awesome and go really far. If you have a 2" barrel, just put a chunk of potato in first and drop the golf ball in on top of it.
Powerade bottle also fit very well in 3" barrels. Just put some tape on the bottle to make a tight seal.
