A log isn't a very good media for testing the performance of a self defense round. What I look for is reliability and accuracy. In my opinion any good bullet designed for defense will suffice. The FBI tests are still the gold standard. Also, remember you are shooting a 2" snub revolver and it may not quite meet or exceed the FBI tests. I would feel well armed with your firearm and 5 Hornady Critical Defense rounds.
For what it's worth, I only use these rounds in my self defense weapons. Reviews are awesome for them, and they're made by hornady. I have yet to find a hornady round that didn't perform or do what they claimed it to. One of my frequent carry pieces is also a .38spl S&W j-frame snubbie.
I know a locust log is a poor choice of media...but it was handy...and made a nice target for a round..
I truly believe that is the design of the bullet and it performed as it should have... Hard target caves in the nose to aid penetration where it would expand in a soft target..
I will try to remember some water jugs next time..I am a bullet junky and will dig out any bullet I can just because I wanna know...
I've tested other rounds in deer parts not fit for consumption and such and always see what the reviews show..gold dots..winchester ranger..federal HTC I think it is..hydrashocks..
Pretty hard to go wrong with any of the major brands IMO...
I feel just fine with my snubby as a back up gun...hit what I point at and 5 rounds of the hornadys is bad news for whatever is on the down range side..
I also noticed the shock of the bullet in the log compared to the lead round nosed I shot into it...it had a defined shock wave..probably when the nose started crushing and the bullet wanted to keep going...
2-3 weeks I plan to shoot again..will try to capture a few more bullets
