In the course of doing some ballistic testing with sig V crown bullets in 9mm I came across Berry’s 124 gr Hybrid Hollow points and thought I’d see how they do for an inexpensive option.
The results were mixed as the bullets appear to have a very narrow envelope where the will perform well.
For example when fired from a 4” Kimber Pro Carry in 9mm at around 1120-1130 FPS. They expanded extremely well but slightly under penetrated coming just short of the FBI 12” minimum:
(The second bullet came apart while digging it out of the gel. They fully expand leaving very little “base”.)
On the other hand when fired from the 3” Kimber Micro 9 at around 1040-1050 FPS expansion was poor to non existent and they slightly over penetrated:
That’s a big difference in penetration for an 80 FPS difference in velocity.
I suspect the sweet spot is very close to 1075 FPS and if that could be attained and then verified in your particular pistol, it would be a good self defense bullet.
Short of that, it would be very hard to predict performance.
