Are there any AR "buffs" in here? If so, I have a few questions concerning ammo, preferences, and why.
I'm a rookie when it comes to this level of firearm so to speak; I'm learning, but to learn, you have to ask the questions!
I'm going to primarily be using 75-77 gr in my 5.56. Due to availability issues with these loads overall, I'd like some input about a secondary round.
I'm looking at either -
XM193 5.56x45 55gr Full Metal Jacket .. OR
XM855 5.56x45 62 gr SS109 Steel Core
which would you recommend and why?
