Today i was trimming, and cutting the grass at the range. When cleaning up i found several nickle size remains of 9 mm fmj rounds on the ground below the steel plates. Which got me wondering about ammo in general, to me the fmj expanded in the sense that it was much larger in diameter, after impact. So now i am wondering if fmj has any expansion when hitting objects other than steel?
Also based on examination of the round it appeared to have lost some of its mass? If so where did it go, as it did not.appear to have fragmented.
