A: Thanks for reaching out Larry! I regret that Australian Defense Industries does not publish this ammunition's ballistic data, so I am unable to calculate its exact BC for you. I can tell you that a 0.151 G7 BC is the typical reference for M855 and SS109.

A: Hello Michael! This blogger does a great job of answering your question – certainly worth a quick read: squibloads.wordpress.com/reloading/get-the-crimp-out
But just to be sure, this ammo's military-style crimped primers aren't important unless you intend to reload its empty brass cases. If you plan to leave the cases on the ground, then they're nothing worth being concerned about.

A: Yes sir, absolutely it will. You will observe the best accuracy out of this ammo with a 1:9 or 1:8 twist barrel, but a 1:7 twist will prove serviceable as well.
