Slug vs. Cut shell comparisons
This is a comparison between a slug and a cut-shell. Cut shells is a practice used heavily in the pre-1930 era. I remember as a child hearing about cut shell and their effectiveness but I have never seen it demonstrated until now. Seems there are several youtube video's on the subject.
Please realize that cut shells are low cost bird shot shells cut. If you can take a bird shot shell and make it compare to a slug that pretty impressive.
