Home Forums Hunting & Shooting AR and Tactical Rifles 300 Blackout ammo?

I just built my first AR and I went with a 300 Blackout upper. I do not reload, so I'll be using factory ammo. Looking at ammo, I'm a little confused. The bullets are all over the place, 110gr., 120gr., 150gr., 220gr., etc. If I'm using it on deer, what should I be using? If using it on pigs, what should I be using? I know that 110gr. are super sonic and the heavier ones, 220gr., are subsonic. What's the advantage of one or the other?

I took it to the range last weekend and was using Barnes 110gr. TTSX. It shot great and had it on in less than 10 rounds.

This is what it is:
Anderson lower
Timney 3 lbs. trigger
Rock River lower parts kit
Radical Firearms 300AAC complete upper with 16" 8-1 twist with Radical Hybrid rail.
BCM Mil-spec buffer tube 2.9oz. buffer
Magpul CTR buttstock
Leupold Mark2 integrated mounting system
Leupold Mark AR Mod 1 rifle scope
