Greetings Gentlemen

This is my first post in the wonderful world of 10mm. 

I was able to pick up a Glock 20 Gen 4 here in California.  A feat in itself mind you.  Anyways.

Bought some Buffalo Bore 180 gr.  Man.  Those are awesome!  Nice kick and they work great in my G20 but they are expensive.

I ran a box of some PPQ(I believe. I don't remember).  They were kinda weak about as snappy as a standard 40SW.

Found some Hornady 180 gr XTP rounds.  Bought 2 boxes for $24.99 each.  I shot one box through my G20.  I picked up empties and out of the 20 rounds, I found these...


Suffice to say I returned the other box.  I remember the Hornady rounds felt pretty weak and I did have one FTE.  Any ideas what caused this?  Bad batch of brass?

I bought another box of Buffalo Bore and the gun functioned perfectly.  Now to buy some Underwood ammo
