Got any 10mm data?

[Fail-Safe]

With respect a test that is not recorded nor with specific details is fairly useless.

Actually, I dont know if it was recorded. The rounds were fired for shits and grins by some cops after a dept ballistic testing which was supposed to be "We swear, your GP rifle round is awesomez". The two gel blocks were left overs.

Yea and that is fairly useless information.

Here is a new TNOutdoors 9 video where he tests the Underwood 10mm 135 grain Nosler JHP.

Amazingly predictable on that 135gr load. In the .40/10mm caliber, the 135gr bullet has an approximately sectional density of only 0.121. Virtually every handgun caliber that has that low of a sectional density rating has almost identical penetration to that tested 10mm load. Usually 9-10" of penetration.

According to the decades proven FBI penetration standard, it is a failure. All that extra velocity pretty much did nothing for the caliber. Bullet sectional density, mass, and construction influence projectile effectiveness far more than velocity.
