School me on 300 Blackout

There's 20 plus AR chamberings other than .223/5.56 plenty capable of taking game at distance?

A 30 Carbine is capable of taking game at distance.  Is a reliable big game caliber?  No absolutely not.  Yes it is effective at close range, but is it a reliable big game cartridge?  No. 

There are MUCH better options for deer hunting than most every round that the AR15 is capable of being chambered for.  There are MUCH better options for a big game hunting rifle or carbine than an AR10.

Besides the energy, the other real trick is matching bullets that will expand at the 6.5 velocities.

What bullets have you found that give good expansion performance at these lower velocities?

Holes kill things period! At 496 yards with a 120gr Nosler Ballistic tip from a 6.5 Grendel 16" carbine. I have watched the bullet pass completely through a mature mule deer. Center punched the lungs, the buck walked backward for 4 or 5 steps after the hit and dropped. Done deal.

Same deal at 302 yards on another buck, bang Flop! He slightly raised his head after he dropped and got another through the throat.

Anyone who is shooting at big game at 496 yards with a 6.6 Grendel has no business being in the field hunting big game animals period.

"MODERN archery equipment is only putting out KE in the 70-80ft/# range.  And the old traditional gear that produces significantly less energy has been taking game for centuries.  placement placement placement.  Take out both lungs and you have a dead animal that will not go far if at all."

Hogwash!  Shoot a field trip through both lungs of a deer and it is more likely than not that it will cover a LOT of ground before it dies.  Archery big game arrows are tipped by razor sharp broadheads that cut a hole close to or exceeding an inch in diameter.  Archers do not rely on expansion of a projectile to cause shock and to expand a bullet, they rely on massive hemorrhaging and a bullet that does not expand may, or may not, accomplish sufficient hemorrhage to result in an animal expiring before covering a lot of ground.

An 18" barrel and heavy duty suppressor takes a .308 down to about 135db.  I wouldn't shoot it all day, but would not be overly concerned about a small number of shots on game.   I have a couple of .300 blackouts and a couple of Ar-10s,  but hunt with an Ruger American Predator 18" .308 and Silencerco Specwar.  I find it much easier to carry in the field than any of the ARs.

Let's get back on subject and stay there. Thanks

Opinions may vary and ours definitely do. You drive yours and we'll drive ours.

411 yards, 16" 6.5 Grendel 120gr Nosler Ballistic tip, put it in there and they die. Alexander barrel I have since reworked the rifle for him. . Make over carbine second photo.

Taylor Knock Out Values were developed by John Taylor as a way to quantify the ability of various cartridges to ensure HUMANE ONE SHOT KILLS when an animal is hit in the vitals.

Here is a site that will calculate them for you.  This methodology was developed after having personal, first hand, experience shooting THOUSANDS of big game rifles.

There are other methodologies, but this one is one of the most widely accepted. 

Thornily is another widely accepted methodology

One or two, or even a few dozen animals are not sufficient to make generalizations from.

Subsonic, suppressed, in an 8-10.5" barrel .300 BLK has a niche.  The modest case capacity and larger bore make it efficient out of short barrels which, when suppressed, still end up fairly short.  The trajectory with subs is very rainbow like and the energy is low.  There are bullets designed to expand at subsonic velocities such as the Lehigh 194 grain and others.  If you plan to shoot subs exclusively you can use a pistol can which is noticeably shorter, lighter, and more versatile than a rifle can. 

If you want the flat trajectory and foot pounds energy of a supersonic load there are choices with much better ballistics than the .300 BLK that fit in an AR-15 sized platform.   These rounds generally need a longer barrel to run efficiently.  You will also need a rifle can and it still will not technically be hearing safe.   However, the Blackout does fine out to a couple hundred yards with 110-130 grain supers even out of short barrels if you want the flexibility of subs and supers in one rifle or pistol.

The attached pistol has a 10.5" barrel and is wearing a Silencerco Specwar.
