I’m a massive fan of the XM177 / Car-15.I have a Colt C-AR SP1 16" and I love the gun. Light and pretty accurate for having a light weight pencil barrel. With a period correct Colt 4X scope or using the peep sights, I can knock down Ram Silhouettes at 400 meters by double tapping, using 55 grain .223 or 5.56 rounds. I consider it one of the best SHTF survival guns you can own. If you can find one for yourself, grab it, you will not be disappointed.
Hog took 11 rounds of 5.56 and 3 to the neck and one head shot grazed off the sloped head. Finally went down.5.56/223 is much more capable if you get away from the original rifling twist rate(s).
The original, and I mean the REAL original was 1 in 14, and it failed cold weather accuracy testing, so 1 in 12 was adopted. 1 in 12 is great, with 55 grain and lighter ammo. But like 22-250, you're stymied by it.
The A2, and later commercial barrels made life much easier, as 1 in 7, and 1 in 8 fixed (mostly) the bullet weight and performance problems of the 1 in 12.
I wouldn't hesitate to use my A2/A4, and other later barreled rifles and carbines on larger four legged game.
You just need to know your rifle.....
So at the end of things you're still gonna be hunting hogs.Hog took 11 rounds of 5.56 and 3 to the neck and one head shot grazed off the sloped head. Finally went down.
I need a shtf rifle to take down big hogs, people and deer.
If city, 5.56 is fine, but I’m going for best for the job, not “will get it done”
Any rifle will work, I want to stack the odd in my favor![]()
