A few pix of the dryer we shot at with my newly made GB cannon. The dryer was on the 125yd mark and a 1/2 oz to 1oz F powder charge, all projos wear golf balls except one lead ball. Only four hits out of ten shots not bad four the first test run.
nice shot of the dimples
all most missed
lead ball
The firing line is actually about 20ft higher than the targets and the balls kept rolling out so a little grass on top helped.
