Nice, I carry my 10mm from time to time. I use the Hornady Critical Duty ammo.
Great Video!!

Good information.

Any way to calculate amount on energy upon impact?


The only handgun I have in 10mm is Delta Elite. In process of getting Dw Titan and Glock 20&29.

Too bad, for me, that H&K does not make one in 10mm!

Nice performance for the XPB. I hope it would preform similarly through denim.

The XPB was fired through four layers of denim.

Great tests. My own opinion is that the XPB may be a bit too fast there as it is apparently losing petals.

Buffalo Bore also makes a low-flash short barrel version of the Barnes 140 Grain XPB that I have tested in an SP101. In the short barrel, the round averaged over 1150 ft/s and penetrated all the way through four one-gallon water jugs. Other reports on the net have shown roughly 16" penetration in 20% ballistic gelatin at those speeds.

For complete penetration capability I prefer the Buffalo Bore 180 Grain Hard-Cast Wadcutter, which appears absolutely devastating and does not lose weight or deform.

But I dare say the 140 XPB is hard to argue with as a hollowpoint, given the characteristics of the round through barriers and the wound channel through gel, but as mentioned I think alot can be said for the lower powered version which penetrates quite well and does not shed weight - retaining a circular petal formation that increased the wound channel and provides a cutting force without stream-lining from the speed. Barnes themselves makes a Vor-tx branded load of the 140 xpb which is loaded to reduced velocities as compared to the hotter Buffalo Bore and Federal versions (with the exception of the BB short barrel load).

I tend to agree. I think it might be useful as a woods defense load in that there is some decent upset in the first few inches, which would be useful for humans and smallish critters, and the petals seem to fold all the way back on the shank, which aids in penetration for bigger critters.

That extra velocity could also be useful for hunters who aren't shooting game six feet away.

Yep.. Barnes markets the XPB as hunting loads, but at reduced velocity it would make a pretty competitive self defense load at 14 - 16" penetration and full flowering of the petals.
