Alf, glad your OK, I too have seen and experienced this many times, been there, done that and still have the tee shirt, actually a polo shirt that I wore over a long sleeve tee shirt, that still has the semi circle cut in it from a 185 grn, .45 semi wadcutter base that caught me in the shoulder 200 yards away, but hard enough I still bled.

I learned and I teach at ranger officer school, you look at where the good shots go after hitting the target and where the bad shots go if missed. Fuzzdaddy is right, about large targets like b27's up close and you hit the groin area perhaps, valid hit, but the angle of the bullet is going to impact the floor, not the backstop, bad enough in the dirt, I'd say unpredictable when hitting hard surfaces like concrete and then the backstop or wall, kind of like being in the middle of a pool table on the break. In class I use sticks at angle through a cardboard target to show the students where bullets will go after hitting the target from standing, crouching and prone, but all hitting the A zone, gets their attention.

Still glad your good to go.
