Just out of curiosity, did you happen to test any 115gr RN FMJ? I'm wondering about penetration depths considering there are quite a few folks, who have expressed in this forum, that they use FMJ for defensive purposes.
It funny that you ask, but yeah, I have tested
one (you'll see why in just a moment
) 9mm FMJ in water- a Federal 124 gr. FMJ at a chronographed 1143 fps from my G17.
Knowing that it would probably blow through a lot of water, I set up about 120 inches of water column (that is 18
one gallon freezer bags full of water set "width-wise" along the length and past the end of the water box) primarily for the sake of seeing just how far it would go.
As might be expected, it didn't deform at all (it miked at a perfect 0.353" +/- 0.001" all the way around and 0.604" +/- 0.001" long) and I recovered it ~77½ inches down the length of the box. Nothing spectacular occurred- just a dozen half-emptied bags of water.
Kind of a waste...
Neither model, Schwartz's nor MacPherson's, requires that non-expanding designs (FMJRNs, FMJFPs, SWCs, etc) be test-fired since it is presumed that they will not deform significantly in water- in order to use the model(s), just use their nominal bore diameters (0.354" for the 9mm, 0.451" for the .45ACP- you get the idea) to get their predicted penetration depths and mass within the perm. wound cavity.
For a 9mm 115 gr FMJRN at 1155 fps (typical factory specs)-
-the Schwartz bullet penetration model says that it'll penetrate to a depth of 26.3 inches and permanently crush 1.073 ounces of soft tissue over that distance
-the MacPherson bullet penetration model says that it'll penetrate to a depth of 28.1 inches and permanently crush 1.152 ounces of soft tissue over that distance
ETA: For those who like to use FMJs in the .45ACP...
For a 230 gr FMJRN @ 835 fps
-the Schwartz bullet penetration model says that it'll penetrate to a depth of 25.1 inches and permanently crush 1.661 ounces of soft tissue over that distance
-the MacPherson bullet penetration model says that it'll penetrate to a depth of 29.5 inches and permanently crush 1.964 ounces of soft tissue over that distance
