The best fuel!!

Don't mess around with hairspray!!
Just get yourself a "bargain Pak" of propane lantern cans at Walmart!!
We tested propane against LP gas, and the propane actually gave a more "Pronounced" report!!! That hairspray is kids stuff, it gums up the gun and makes a mess!!! Get a cheap "autotorch" that screws onto a little propane cyl. and have some fun!! Give it about 6-8 seconds with the nozzle in the chamber, then close it up and, BOOM!! Does anyone have comparisons between using 3" or 4" for the chamber?? Or 2" or 1 1/2" for the barrel??
We have a real good shootin' gun now, It's ONE FOOT of 3" for the combustion chamber, and a 3 FOOT barrel of 2 inch!! It is a good, and, simple formula to go by!!
