This cannon was pretty extreme. It shot a golf ball at speeds approaching the speed of sound and has some SERIOUS power.

We typically used around 1 ounce of powder charge, enough to propel the ball clear through a bucket, and into the dirt.

Electrical ignition was not bothered with, used long fuse
