They sure do, these shells are .308 and I have hit them with my FX Cyclone with JSB 15gr pellets and bent them up pretty good.
Today I went to the range with some .22 Metalmags.
Using my HW 97k, shooting right in at 650 fps. After a sight in session I thought I'd try shooting some shells off the floor. I hit the chrome 9mm shell and heard it hit the floor. By the sound I knew it had penetrated. To my surprise it went through.
So I thought I'd try the .308's again with the Metalmags.
Wow, pierced right through the other side.
