If you want to have fun with the .475, shoot some water jugs but stand back a little or you will get a shower.

It blew 4 jugs sky high, split 2 more and went all the way through 14 jugs. We thought we could catch a boolit but it looks like we need 20 jugs. My almost WFN penetrated 37" of soaked phone books and paper.
The gun is just too much fun to be legal!
