Tested Hornady 165 gr Critical Defense and Precision Cartridge 180 gr Golden Saber today. I'll probably post the pics and video as well as bullet measurements tomorrow if I get a chance to melt the blocks down but here are the numbers from today's test:


BB calibration: 599.3 fps, 3.6"

10mm Hornady Critical Defense 165 gr

Velocity, penetration

1,135 fps, 12.6"
1,148 fps, 12.2"
1,148 fps, 12.8"
1,144 fps, 12.7"



BB calibration: 594.0 fps, 3.75"

Precision Cartridge 180 gr Golden Saber:

Velocity, penetration

1,161 fps, 13.8"
1,150 fps,  (this one actually angled up a bit and left one block, then left a small mark where it hit the second block and I couldn't find it)
1,162 fps, 13.8"
1,139 fps, 13.7"

I'm going to add them to the master sheet. So far it looks pretty good what we are seeing. I still can't believe we get people making comments about 10mm over-penetrating!

I think that is mainly due to the fact that most folks have no clue how modern bullets work or how velocity effects expansion and penetration. Sure, a 220 gr hard cast from a 10mm will go stupid deep. Of course, a 230 gr FMJ from a .45 will get pretty deep, too.

The GS bullets look like at least one of them turned face down in the Gel.

Neither of these looked up to speed, so it will be interesting to see some of the ones that are!

Yup, they both came to a rest not facing fully forward. Definitely weak sauce for 10mm but I'd say either of these are perfectly adequate for defense.

Yep,155's did their job.

Which 155's?

Sorry Intercooler.That was supposed to be under "RELOADING 10mm AMMO"catagory response.My bad.

Good stuff.  I still like the UW 155gr GD load best of what you've tested so far.

I got 1365 and 1301. We are similar for the extra barrel length on the Match. Don't know why I got so much more on the PBR. What spring is in your Match?

My Witness is the standard model polymer frame but I have the 22# spring.

Thanks Raggedyman!  And still, so far I like the UW 155gr Gold Dot load best.

 Any videos spooling up? Maybe Atomic and Big Ted?
