Sorry bout this being so much late but I just rad the thread. I have built 7 7.62x39 ARs in the last few months just for me and my kids. All have BCA barrels and several different BCGs, whatever I could get my hands on. I still have my 65 grendels, but components for ammo got SCARCE and I could buy 7.62x39 124 gr and 154 gr SP in bulk for my deer hunting and coyotes. My ARs in this caliber all shoot close to MOA out to 150 yds (124gr) and 200 yards (150 gr Hornady bullets in wolf/tul cases with 154 gr sp pulled and replaced with .308 Hornady). I found that .308 Nosler 125gr Ballistic Tips also shot MOA when 124 gr sp wolf or 124 gr norma FMJ were pulled and .308 125 gr BT replaced. I use the lee factory crimp die and the .308 dia bullets work very well. Have not chrono'd yet due to not wanting to waste bullets. What I did do was use gallon milk jugs filled with water at 100, 150 and 200 yds. The wolf/tul 124 gr sp quit exploding the jugs at 150yds, 125 gr nosler quit at 150 yds, 154 gr wolf/tul quit at 150 yds. The 150 gr hornadys still exploded jugs at 200 yards with 1008 pounds energy by nikons ballistics chart. I am going next to 135 .308 FXT in wolf/tul 154 gr pulled cases. All barrels were 16" hvy. 1 on hand assembled Anderson lower with Velocity 3.5lb trigger Anderson upper receiver. All the others with Anderson upper receivers and Omega Poly lowers with Mil-spec tubes for weight reduction. LOVE'EM!!!
