thank you for creating this masterpice it is a work of art that it was able to do that qustionn though did you use actual patatos or solidor hollow core projectile becase if it was solid or hollow core then i did something similar by using a bead seater based air cannon with 1/1/2 in steel pipe with 2 steel nuts in front and back with a rebar welded to the front if you want to pentrate more steel than i whould suggest using something similar to what i did and thank you all and is there any way i can help you
