Did my military service entirely in CONUS, so I've never shot anybody. I've just been hearing and reading that the reviews on the M4/M16 are mixed. The official opinion, of course, is that the 5.56 is the deadliest round in history, but the Army has considered adopting the new 6.8mm SPC cartridge, at least for special forces. The 6.8 is supposed to give the rifle better range and terminal ballistics while replacing only the barrel, bolt, and magazine. Somebody who's shot people with the poodle shooter must be dissatisfied with it.

While they're at it, why not dump the 5.56 x 45mm poodle shooter and go back to 7.62 x 51mm?
