Textron's easily. I really want to fuck around with CT. Had a machining project sitting in the back of my mind since I first learned about ACR and having a production rifle and ammo would let me actually implement it. >>49211209
NAYRT>Loading for accuracy doesn't require reuse of cases and will be easily supplanted by polymer cases being so cheap that long range freaks can just use a fresh case for each.
That assumes you can load it all though. It might be that you can't handload at all, and the bullet has to be seated during molding. If that is the case, then you're stuck using factory ammo (which is less than ideal even if their claim to better accuracy due to consistency is true) or sticking with brass.
Not that it matters, brass isn't going anywhere even if polymer becomes popular.
