Hi All,
Happy July 4 and July 1 Canada day, I made lots of racket up here north of the border on Canada day and the 4'th !!
I am in the process of building a new cannon for golf balls, here are the specs, 3" x 1.70 DOM tube 26" long, 6" solid bar breach plug with a 1" dia. X 2" long powder chamber with a shrink fit in tube, chamfered 3/8" and welded at back end , 12" long x 3" ID. 9/16" wall DOM tube outer sleeve press fit and welded both ends over inner tube. Hope to shoot about a max of 400 grains FFG for long range target shooting. Safe?
