Most people will just say bump to AR-10 or 300BLK for silencer but what is the best overall AR-15 caliber?

5.56
300BLK
GRENDEL
SPC
SOCOM
Beowulf

My guess is probably gonna be Grendel?

How does the SPC and the Grendel compare?

We've ran the 6.8 SPC to 700 yards, and attempted 800, it just won't get there.

We've ran the 6.5 Grendel to 800, and even shot the little 1 MOA plate at 800, reatedly. 6.5 Grendel has the higher BC, which maintains velocity needed for distance, and is less affected by cross wind.

6.5 Grendel is THE long range AR-15 round.

Yep, I am a huge 6.8 fan and have 2, great for normal Texas hunting deer and hogs inside of 300 yards, but for long range, get a 6.5 Grendel with a match barrel and go to town. JP rifles makes an outstanding upper and have shot that to 1k.

For deer, hogs and varmints I'd vote for the 6.8. My daughter and I both killed our deer this week with 120 grain Hornady SST. She double lunged her deer and it was DRT. I took out the heart and lungs and my deer took two steps and dropped. I'd feel confident shooting out to 300-400 on any yote or hog with this round/gun. High quality factory ammo is readily available and it's cheap.

Out to 300yds, its a wash. After that the Grendel will start gaining the upper hand.

Love my 6.5 Grendel. I also have 5.56, 300 blk, and .458 socom.


It is far more important to be able to hit the target than it is to haggle over who makes a weapon or who pulls a trigger.

6.5 Grendel if you are truly looking for a long range gun. For typical Texas hunting within 200 yards, 6.8 SPC.
