Thanks for the input Guys.

I changed my spark source and WOW!!!!!!!
Guess I had a weak sparker?????

Thanks again

lowest pressure that would fire gave me 25 yds. pound by pound increase til i got 50 yds. Then dramatic fall in distance. checked for leeks
in the chamber and in the meter,none.

Thanks

Hi All

Just joined. Been reading for a while now.
I was wondering aprox distance I should get with my cannon?
metered propane,3in X 24in chamber with a 1.5in X 4ft barrel.
I have been trying different psi in my meter. My best distance so far
is 50 yds
