Ruger 10/22 .17 Mach 2 vs concrete block
January 1 2017
A Ruger 10/22 chambered for .17 Mach 2 equipped with a Rocky Mountain Arms sound suppressor is used to determine what 17 grain Hornady .17 Mach 2 ammunition will do to concrete blocks. Two rounds were fired at each hollow core portion of the two blocks placed on the test stand. The 17 grain .17 Mach 2 ammo showed approximatly 3/8 inches of penetration into the face of the blocks. No interal damage was noted on any of the cores of the two blocks.
