10mm FEDERAL HST is Weak!

Chrono velocities were terrible.

Good video AB!  It seems only a very few ammo makers are interested in top end 10mm loads.  Maybe they just loaded it for the optimum speed of the HST bullet.... being 40 S&W velocities.  Anytime you see a G40 OEM barrel giving the same MV as the KKM barrel you know it is very lightly loaded on purpose.  The 155gr Hornady XTP's are quite a bit faster but not as fast as Underwood's. 

Thanks again for your video's

Hence the reason I Love Underwood's stuff : )

Thanks for sharing your data points with us.  Unfortunately your results are in line with similar velocity tests of this stuff.

I'll pass. 

Hopefully they'll make the projectile available to the market for reloaders and Underwoods of the world to load appropriately. 
Won't hold my breath but maybe someday...
