I tried Monarch brand 115 FMJ steel case because they were cheap at the range. These are the first rounds I have ever used where I had to wash my hands because they caused my hand to turn a funky looking green after 200 rounds. I shot 150 of the brass 115 grain FMJ's and no residue on my hands, but I cleaned the gun before shooting them and got a lot of gunk off the weapon while doing so.

I ran 200 rounds 100 were through my Glock 26 and there was one failure to fire but I had three in a row (well on three consecutive range visits there was one failure to fire) so I am gonna have a gunsmith look at my Glock it did this with other ammunition also so it could be the firing pin isn't correct or something along those lines.

Other than that I shot great with both weapons but get ready to wash your hands after a few rounds at the range it must have something to do with steel and exploding gunpowder that causes the weird residue on you hand!
