The 9mm FMJ proved to be the most accurate and my current favorite after testing it. I have been wanting the 9mm JHP version for gel and found the .357 Magnum 158gr to try as well. They both look interesting!

Those were interesting...they have a line of competition ammo or make it for competition shooters.
I bet these will do pretty decent in gel.
