Thanks! Although I only shoot handloads, my latest batch is close to this spec.

Your videos keep getting better. Keep up the good work!

By FBI spec, does that mean you calibrated the gel with a BB? Because 32" is a whole lot of penetration for 5.56mm, even a bonded one. It sounds like your gel might have got a bit warm or in some other way isn't matching up with the FBI gel.

No, they make several types of gel (some for arrows, dummies, and bullets). Their bullet gel is called "FBI spec." I calibrated it as I do every time (per mfg specs) and almost all of my tests are within 1-2" of ammo manufacturer published data.

Other tests have reported very similar penetration in actual ballistic gel so I think it's a good representation of what can be expected.
