I tested 9x18 makarov buffalo bore 95 grain JHP and Hornady 95 grain Critical Defense FTX
I just recently got a cz82 and was interested in conceal carrying it and i recently learned how to make ballistic gel so I figured i test some of the popukar defensive rounds for it.
I used the FBI standard 10% block and had 4 layers of denim in front of it.
The first picture of gel is of the side that I shot 4 rounds of buffalo bore into. As you can see it stayed very consistent between 14 to 15 inches and all of the JHPs expanded well.
The second picture is the side I shot the Hornady into. It did penetrate further into the gel with the furthest being about 21 inches and the shortest about 15 inches. As you can see expansion was not consistent and only 2 of the rounds really expanded well with one having almost no expansion. You can also see the FMJ at the top of the gel that I shot into as kind of a control.
The final picture is not the best but the right side is the "wound" channel of the buffalo bore and the left is Hornady. The buffalo bore left a much more violent channel than the Hornady. Another thing I noticed is that I could shoot the gel block with Hornady and not have to worry about it moving around where with the buffalo bore I had to tape the block down to keep it from jumping off from the table.
Just from my little test I definitely feel more comfortable with carrying the buffalo bore but I am no expert and im sure there much better testing out there.
