I really liked the idea of the FMJ's, so I bought a 1/2 doz 400s to try them out. I really like their look and the way they shoot in the wind, however because of the aluminum skin they will keep a bend. I kept three aside for targets, and tipped the other three with G5 SGH. All of my target arrows are just as strait as when I brought them home, but two of the 3 that I have been small game and stump shooting with have a very noticeable bend. In my personal opinion the aluminum skin isn't what isn’t cracked up to be.
