Obviously shooting water is not gel or people or animals, but I have noticed some disturbing trends. The last few times I shot water jugs, I had some shocking results. Both 70gr GMX 5.56, and 50gr TSX Black Hills (factory load with the LE bullet) 5.56 fragmented and veered/tumbled. The GMX was kindof the dark side of the moon to me, but when the 50gr TSX fragged and tumbled from a 16.1" barrel, I began to wonder...does water cause projectiles from rifles with hollow-point design to over-expand/expand more violently than actual tissue? I would presume not, as tissue is actually denser, but...? Are these rounds likely to frag in tissue, if they are fragmenting in water, or is that the wrong conclusion to draw? Why/why not?
