I’ve got an Armalite AR-10 .308, 16” barrel with either a 10” or 11.25” twist ( I haven’t decided which yet). I’ve been testing 165gr bullets, with decent results. A couple loads will produce 1-1.5” groups, but most are 2-3” groups. I am tempted to try 150gr and see what happens. What weight bullets do you guys shoot in your AR-10’s?
