FMJ's not accurate? Depends on your gun and the ammo. Some FMJ's arevery accurate. Speer lawman 180 grain in my Glock 22 is super accurate. Winchester White Box in my Springfield XD is very accurate. Federal Eagle .308 FMJ will shoot 1" groups at 100 yards in my T/C Encore all day.

The reason we don't use them for hunting is because they do not expand like we need them to. We need a bullet to expand and do damage to kill game such as deer. A FJM will go right through and never expand unless it hits a major bone, leaving no energy just a nice .30/.6mm/.35 hole.
