Because it it proved rather effective. If it was something other than M193, M855, or 55Gn SP, it's a rather large statistical sample of ACTUAL shootings with a given bullet for a 16" Carbine.  Just becasue something was a horrible crime, doesnt mean the wound ballistics and LE community cant learn from it.

The ammo used is probably what I am most interested in knowing. for reasons given by those who also want to know.

... Maybe not, I read somewhere today that a healthy portion of the jurors are retired Military.

Geez he could have really dazzled them puttin' the bolt back in a bolt action rifle. Wow did ya see how fast he did that. And he had the bolt hid in his underware.[shock] Haa!, I can kill you all now with my semi-automatic bolt action rifle. Haa!

Thanx for the pic.

I saw the USA DC Sniper show, and it had an A2 stock in the movie as well as a long regular scope. It didn't look anything like this one.

I hope they fry these guys. What horrible crimes.

I remember they showed one of the spent casings.
It was a Remington R-P .223 headstamp.

I'm assuming the load was run of the mill UMC 55 gr. FMJ

Ha, I didn't mean the pun there, but it is rather funny.

There is nothing about the facts of the gun, optics or bullet that get me "hot and bothered".  IMO, it was a stupid choice of rifle to use for what he was doing anyway.  A good 30cal sniper rifle would have suited the job better.  As the other posts by balistic experts on this forum try to say, you cannot make a sound conclusion of a rounds effectiveness from a few random shootings.

Well DAMN!  That stuff must be the best ammo in the WORLD.  Look how many people it killed.  I'm going out and buying 5000 rounds RIGHT NOW.

As for the round used:

1.  Can anyone confirm that it was indeed Remington UMC 55gr?  Where was this case headstamp seen?

2.  I haven't checked the exact details of each shooting, but if I remember correctly, all of them were good CoM hits.  Snipers in the middle east have utilized .22LR with good results.  Good shot placement can often times make up for a lack of terminal ballistics.  Some people seem to think it's the other way around... [;)]

3.  Here's a bit of testimony from Paul LaRuffa:


[i]Holding back tears, LaRuffa described in detail what happened after he closed his pizzeria and got into his car on Sept. 5.

"I saw a figure to my left. I saw a flash of light," he testified on the second day of the trial. "The window broke. I heard shots. I was being shot. I said I wasn't going to die. I said, 'I'm not dying in this parking lot in Clinton, Maryland."'

In addition to the chest and arm injuries, a bullet fragment lodged right next to LaRuffa's spinal cord.

The victim said he realized shortly after he was shot that he was bleeding from both the chest and the back.[/i]

Take what you want from it, it's hard to tell exactly what was going on here.  I'm not sure if he's saying there were multiple shots or just one.  It's also hard to say if the round or rounds actually fragmented or if it was only the rounds that passed through autoglass that were ripped to fragments.

REL: Paul La Ruffa wounding....This is Muhammed & Malvo for sure; but no Bushmaster involved.  This was a "close-up", store receipt, robbery-stick up- and the weapon was a 22LR handgun. They got about $3500 and this was their bank-roll for all their later activity. They never requested money; came up to manager's car and shot him 6 times "point blank" and grabbed his bank bag.

Thank you for clearing that up.  That was information that I did not have available to me.  I was just posting what I found.  Thanks again.

They showed it on MSNBC,CNN, or FOX? take a pick.
Just saw the headstamp. I'm just guessing it was UMC 55gr.
