wadcutter will blow through more than 12" of 20% ballistic gelatin.
I think a 25acp and or a .32acp will blow thru at least 12'' of 20% ballistic gelatin under the same conditions. (I better fact check that.)
When 12inches of 20% ballistic gelatin develops two legs and gets an early release from the California Penal System for good behavior, I'll take a second look at that YT clip. Keep those YT coming. No one loves YT more than me.
