I was curious with the power and balistics of what energy is left at 25 yards with my .22. I know muzzle energy it goes through 3/4" plywood like butter. So I setup a double walled thermos down range. This test was done with Daystate Wolverine that pushes 18 gr at around 890fps.
The first shot was pure lead dome JSB 18gr, it went through the first side and dented the 4th 'wall' of the other side and then fell inside the thermos. The impact rotated the thermos so for the next shot I put a cinderblock on top and used a Gamo rocket ball tipped pellet, 14gr or whatever. It went all the way through and kept going, clean holes compaired to the massive dent the soft lead JSB did on impact. Talking about stainless steel here...very capable energy to put a hole in whatever is there.
