    Powerful Homemade .785 caliber Copper Rifle

    These videos are several years old but I wanted to share them to anyone who may be interested in making a defensive weapon from easily available materials. (3 Videos)

    I have gotten pressures up to 650 psi and shot a 3-1/4" x 180 grain nail (10p) dart through 3 layers of 3/4" plywood from a muzzle velocity of 900 fps.

    A 10 gauge shotgun's bore is something like .775.

    A pretty interesting air gun.
    “No possible rapidity of fire can atone for habitual carelessness of aim with the first shot.”

    Theodore Roosevelt, The Wilderness Hunter, 1893
