300blackout with 150gr hornady fmj

[JeffreyDeGraff]

So I went to my friends house last night and measured the throat on all 3 of his blackouts. Ruger American Ranch, 8.5” AR, and a 10.5” AR. The shortest by far was the Ruger (they have really short throats). The max COAL for each was, Ruger - 2.024”, 10.5” AR - 2.202”, and the 8.5”AR - 2.062”. So even hornady’s new OAL in the 10th edition is long for 2 of these guns.

Out of curiosity, what is factory ammo OAL?
