Tested those Federal 138 grain SJHP 9mm hollow points on jugs of water and while they partially fragmented, they didn’t expand. One gallon milk jug of water and then three antifreeze bottles. Four jugs in total. Should have taken a pic, but I didn’t. Bullet lodged in between the 3rd and fourth jug. Didn’t expand, but there were blue fragments in the 3rd jug. Kinda disappointed that it didn’t expand. Anyone else shoot this stuff?
