I saw this done on one of the outdoor channels, but it was to see which rifle caliber would penetrate the fastest. I can't find anything on YouTube. I think you've given Lovemywoods a new review to consider.
I have a stack of probably 300 or more red bricks in the drive way. Come get em!!!!
If Lovemywoods would be down, I would swing by Hamsterstyles house and pick up the bricks, head down and do some testing!! I have the week of Aril 4th off
We could test .22 subs, .22 standard .22 cci minimags, .223 from 16" barrel and whatever else they have. 7.62x39, 7.62x54R, .40 FMJ, .40 JHP, 12 guage bird shot, slugs, and 00 buck.
