I want to make a huge block of ballistic gelatin tomorrow, for the next video.
In order to compare the penetration of various ammo, shot at the highest possible speed, I ordered some ammo types I either ran out of or never had. 10mm, 12mm, 20mm, 30mm!
Kugel-Winnie, my trusted supplier, surprised me by adding (at no charge) some 38mm and even some 60 mm steel balls.
I still have enough 8mm, 15mm and 25mm steel balls, plus some .54. .62 and .75" lead balls. So I should be rather complete.
I don't really know yet how to include the 38 and 60 mm ammo... but I will find a way!
