I didn't shoot FMJ's. I shot 125gr HP's. I wanted to see if they would expand in perfect conditions. They did not. In my extensive testing, I've never seen a round that wouldn't expand in water, do so in flesh. Mock the "milk jug test" as much as you want but it still gives you a better idea of what the round can do more than the paper target at your average indoor range.
NVRMIND, I see this has been addressed.
I'm a fan of Paul Harrell's meat target for simulations.
