The Federal TB 10mm load has been unavailable, starting shortly after it was released.
What grain bullet you shooting in .40, those velocity numbers seem high?

Likes pretty much everything in every caliber.

Figures about the Federal load.
Those numbers are from the 140gr Extreme Penetrator I bought from Underwood. The gun has a 6" bbl which surely helps.
Ha, I read Glock 40 as "a Glock in .40," as opposed to the model 40 10mm. That explains why the velocity is so much higher than the 1,200 fps Underwood shows for the .40 S&W load.He said Glock 40 as in a 6" 10mm.

Lol! I would have written Glock Fotay for a gun in that caliber. Or maybe now that I own a 10mm finally I can be like the 10mm snobs and call it 10mm Kurz.
Back to the topic at hand - any suggestions for a test medium that would give an idea how well the ammo would perform on a skull? Is there a thickness of steel that I should use? I'd be perfectly willing to sacrifice these: https://www.amazon.com/gp/aw/d/B0118...ALL&ref=plSrch
Maybe put them in a frame with space between them and see how many (if any) it will penetrate?
Doc has suggested in the past that bullets that do well in the auto glass test are likely the ones to look at for that sort of thing.

I can do that but after seeing the video where this particular bullet zips through bulletproof glass with ease, I figured a windshield would be a walk in the park. Just so we are on the same page, the bullet in question is a solid piece of copper. It doesn't have a jacket that a windshield could try to remove.

Just saw he did a couple other videos with the bullet proof glass. The 9mm Lehigh Defense Extreme Penetrator failed to get through. He mentions that 500 Mag, 5.7, and 454 Cassul did get through.

If I understand correctly, bulletproof "glass" can actually be polycarbonate. Although a projectile that can penetrate such barriers may due well against bone, polymer is not silicate glass. Speed is required to defeat "bulletproof" barriers. Obstacles like windshields are good at impairing lightweight bullets even when impacting at high velocities.
Also, I think the +P+ version of that Lehigh 9mm would have given a better showing for that reason.

At the 28 minute mark the +P+ loading penetrates IIA body armor that defeated the slower +P round.

Even monolithic bullets are negatively affected by laminated glass.

That's a hollow point bullet though. We already know from Doc and others they don't do well through auto windshields. The EP bullets won't collapse the nose or have the petals stripped off. I'm happy to shoot them through a windshield but I'd have to use clear jel. I don't have access to the good stuff.
