Does anyone else own an M4 style weapon that has this twist rate? If so, what ammo does the barrel like? I don't plan on shooting any further than 350-400 yards max as I am just using iron sights or a Aimpoint with non magnification.
Need two reccomendations
1. Target ammo that is brass and not Wolff for practice.
2. Best hunting round out there for killing swine and varmints and every once in a while maybe a whitetail with this kind of barrel.
I live is Texas so that's why I'd like to know what works well on swine. It's a smith and Wesson m&p rig.
