:grin: well I shot my mortar today 2 and 5/16 inch bore 12inches long. And I want to thank everyone who helped with all the info. 1st I just shot it for the sound for the 4th of July we had at the house, but then went and shot concrete projectile in it, and wow still playing with the load, but that baby will zing out there. So once again thanks for the help, you guys are great.
