Here's the situation.  You'll be hunting hogs and only have one of these 2 options:  11.5" in 5.56....or 8" in 300blk.  Super thick brush, so nearly all shots will be less than 50 yards, meaning headshots (behind the ear) are relatively simple.  Also keep in mind hogs will weigh less than 150 lbs.  You already own other carbines in 5.56.  So do you choose 300blk due to the increased effectiveness from a shorter barrel?  Or do you roll with 5.56 and avoid adding a new caliber?

8" 300 BO with the Barnes TSX bullet seems interesting.

Get both. Wait, I already have both. If you don't have both, I'd say get the 300 first just for kicks and suppressor fun(the one thing my budget hasn't allowed for since I built my 300BLK ).

Chasing a moving animal in thick brush? I think our definition of "relatively simple" differ slightly.

I'd roll with the 5.56.

300 blackout is cool but I don't reload.

5.56 always.

If the SHTF, which of those two loads will be easier to find?



Also, 9" is the ideal barrel length for .300 Black.

Understood.  Let's say you're shooting position is stationary & elevated, like a treestand or truck bed.

Remember they are both the same gun except for the  barrel.  Hell buy one then the barrel for the other if money is tight. Get 308 can for use on both.

I have both - except my 5.56 gun is a 12'' and my 300BO is 8.5''. The 300blk is more versatile as a whole. You can have 110-120gr loads at 2100-2300fps that will dispatch just about anything you'd need it to - or you have the 190-220+gr subs that when paired with  can makes incredibly quiet shooting. The Lehigh 194gr maximum expansion does very well even when subsonic.

If I had to pick ONE - it would be 5.56 only for ammo availability/costs. All other things equal, I'd take 300BLK all day every day. With the 12'' AR I was getting 2800fps with 62gr ammo - about 1080 ft/lbs muzzle velocity. With the 300blk, 120gr Remington factory ammo was pushing 2150fps - which is 1232 ft/lbs. 150 ft/lbs more energy than 5.56 with a barrel 3.5'' shorter.

Pretty wacky comparison in that you threw in the "already own 5.56 carbines".   .300 BO is flat out better in shorter barrels with heavier bullets.

Literally this for me too.

In that scenario. 300blk. I really like mine.
Link Posted: 8/31/2015 11:01:57 PM EDT
I understand this is a VERY specific scenario.  I've had good luck with headshots from 16" in 5.56.  For the record, I'm thinking about a pistol in these 2 flavors, so that's my reason for the post.

5.56 loses its effectiveness from a shorter barrel at range, but up close like that it won't make much difference.


11.5" 5.56 for me.

That is true more so with FMJ, but with modern expanding ammunition, not nearly as bad.

I always vote for:  Get both.
