Did some hillbilly ballistic testing this weekend with some 9mm I happened to have sitting around in my closet. They were the Fiocchi extrema 124 grain using the well respected hornady xtp, some old school Winchester 115gr silvertips, and some lowly Remington umc 115gr walmart special ammo. All standard pressure stuff fired from a G26 through 4 layers of denim into gallon water jugs at about 15 ft. I was somewhat surprised by the results.
The Fiocchis failed to expand through the denim penetrated 4 jugs and flattened out on a log set behind the last jug, a second shot without denim expanded perfectly. I was surprised the xtps failed through denim as they seem to do well in other tests I've seen.
The silvertips expanded well completely destroying the first jug and was found in the 3rd. The expansion was somewhat asymmetrical with part of the jacket peeling away from the core but still staying attached. These performed decent but they're as expensive or more so than most more modern premium loads that perform better like Federal's HST.
The UMC surprised me as well. I didn't expect much from Remington's generic hollow-point offering but it expanded nicely and penetrated into the 4th jug. These also shot well out of my g26, I'll probably buy more to keep on hand in bulk as a back up, but I'll still be carrying my 124gr HSTs.
The recoverd bullets are in the pic below from left to right the 2 Fiocchi bullets, the silvertip, and the umc.
