Did some wetpack testing this weekend.
I had some 40SW Black Talon 180gr and HydroShok 180gr ammo on hand and decided to take the bullets out and load them in 10MM at 1300 fps. I shot them into wetpack and lets just say they were NOT designed for 1300 fps ,both disentegrated.
Expansion on the BT's was consistent at .500" x.500" but the jackets shed on all 3 bullets.
Weight retention, 121.3 gr - 127.2gr

Yep, they were developed around the FBI protocols of 180 grain @ 950-980 fps...even those that were loaded as 10mm's were in the 980 fps range. They performed well for what the criterion as set-forth by the standard to help eliminate over penetration. I carried them in my 1006 for years being some of the only factory ammo I purchased for 10mm. They would not be my choice today based on my personal experiences.
Handloading the 10mm cartridge since 1990, has shown many bullets not living up to true velocities the 10mm is capable of. The bullets which have the widest performance window are the Speer Gold Dots and the Honady XTP's. I think the 200 XTP's are better for hunting applications. Although it will be nice to evaluate the Speer 200 GDHP's over some full potential loads!
Many bullet designs shed the jackets leaving the cores to continue to travel deeper or through. This separation or over expansion happens quicker at higher velocities, petals shed off or roll back beyond maximum expansion sizes when exceeding the manufactures' design criteria. Bonded core bullets really help in this area to deliver the full impact to the intended target.
Here is the Hornady 210gr XTP I sized down from .410-.406-.400". I shot this is my G20 SF with a LWD- 5.47" barrel. Load was AA7-11.0gr =close to 1200 fps ,I need to chrony the load.
Weight retention very good
194.3gr - Diameter .547 x .596"
202gr - Diameter .629 x 590"
197.2gr - Diameter .576 x .604"
Penetration was a solid 12"

If the 10mm has more of a rebirth to the shooting world maybe some manufactures will make some GOOD bullets that are designed for true 10mm performance.
I can hope

Yeah the HydraShok isn't one to stand up well to extra velocity. I pulled some and only ran them a little faster (~1,100 fps) and it was frag city. Oh well, I guess that's why I only load a few JHP designs up to 10mm velocity because a number of them can't handle it.
Not too surprising knowing the velocity level they were originally intended for. I think SilverTips hold up better than these Talons.
