Curious about thoughts on this Underwood load? 

Haven't seen any ballistic gel testing but 2100fps  :o

I saw that and bullet loaded in 9mm and was pretty interested. I'd love to see if they can get it working in 9x25 Dillon. I was guesstimating 2300-2400 FPS. This reaffirms I need a 9x25 Dillon barrel for my Witness Hunter.
