Interesting article about Congressional push to choose between M855A1 and Mk318. The Marines are rightfully concerned about M855A1's damaging effects on rifles and reliability, which would seem to favor Mk318 over M855A1 in terms of life cycle cost.
I don't agree with Larry Vickers' comments about terminal effectiveness, especially when it comes to barrier blind performance. However, based on my personal experience with the media, I suspect many of his comments were omitted and the ones that were chosen for the article reflect a very narrow viewpoint.
