Why hunt with a SHTF AR15? Its simple, they are tough buggers, easy to shoot, easy to clean, very accurate and versatile. Whats the down side? They are expensive….compared to your average hunting rifle….and some of the attitudes exhibited by other ignorant hunters.
The two AR 15’s I normally hunt with the past few years are a 6.5 Grendel and a 50 Beowulf. I use to hunt with an AR 10 .308 cal, but the two mentioned above are lighter and more reliable. The 6.5 is a 300/350 yard Caribou gun and the 50 is a 200/225 yard moose/bear gun.
This year for caribou, I have decided to use my current SHTF gun. It is a LWRC M6A2 with 16” bbl chambered 5.56. http://shop.lwrifles.com/product.sc?...&productId=145 It is my work gun and my “GO TOO” gun. I bought this gun 1 ½ years ago to replace a colt (6920) I was previously using. It sports a Trijicon ACOG 4X TA31 ECOS. I also have a quick detach bipod which is great while sitting from strategic locations. It comes off in 2 seconds for the hiking trips. I also have a quick detach flashlight laser M6X which goes on the weapon at night for the 4 legged teeth & claws. A quick detach system for the sling which is a V-TAC two point. Slings are great but sometimes are a pain so I like the QD option.
I had Bill at Pro Tec in Fairbanks set this gun up identical to a demo he has there…in case you would like to see one up close.
The bullet Barnes 70gr TSX
Winchester brass, New
Velocity-20 shot average 2791
5 10 shot groups Best 1.25 worst 1.95 @ 100yards
OK, is 223 to light for Bou? I don’t think so, especially if you keep the range inside 200 yards. The Bou (average bull) I killed last week lasered at 216 yards, the bou was quartered away to the left. One shot. The the bullet hit the 2nd left rib from the back then traveled thought the upper part of the heart, clipped a lung then exited out the right front just missing the ribs and right leg. The bou dropped within 10 feet of where shot.
I was surprised by the penetration of this bullet (even on this thin skinned animal). My ballistic charts say the bullet is traveling 2180fps with 735 ft lbs upon impact at 200yds. But to hit a rib, stay intact while opening up and then completely exit was quite interesting.
One thing I learned about my rifle is that it will shoot the BlackHills 77 gr Match king bullets identical points of impact as my hunting bullet out to 300. The BH 77gr shoots a lot tighter groups then the TSX. Good stuff to know about ones rifle.
I was happy with the results so far. Then again the right bullet for the mission plus shot placement will always work in ones favor.
I’ll just have to shoot a few more tasty fury animals to determine if this was a fluke. I have a feeling the results will be the same. YUM,YUM
