55gn & 62gn seem to be about the only weight FMJs I can find in .223. Are other weights available? |

Quoted:
Why not look into HPBT (hollow point boat tail) bullets? this. i ordered some 77gr seirra matchkings from midway, but when they got here the box says to only use them in 1:7 and1:8 barrels. i planned on shooting these out of our a1 clone, which is 1:12 i believe. ohh well |

They will tumble through the air and keyhole on the target. I learned this the hard way with 62gr m855 bullets in my Rem 700 which also has a 1:12 twist. At first I thought it was the crappy ammo, then discovered they shot fine in my Mini 14 (1:9 or 1:10 twist.) |

Get a buddy with a spotting scope directly behind the shooter to watch the bullets describe a pretty spiral as they fly down range. He'll be able to see the wake. Might need to shoot 300 yards or more to see the wake. |

Maybe, but it's not the way to bet with that short barrel. Standard length 9 twist barrels are right on the cusp where they might or might not shoot 75 and 77 grain bullets. The Sierra is a little shorter than the 75 grain Hornady HPBT. You're giving up lots of speed with the short barrel, speed that is needed to make up for the slow twist barrel. |
