I do recall doing trials of ammo with the L34-A1 and L96-A1..............7.62x52 or .308Win (to our American allies)
Some of the nicest ammo was the Norwegian Raufoss, but the Salt Lake City National Match was brilliant until the temp went over 80f.
I guess that for sniping in Iraq I would look to Raufoss 185gr (yellow label) and a 1 in 10 twist barrel?
Well, actually, "purple spot"...........no one takes snipers prisoner do they?
:D
