The AR 15 has a reputation as a SHTF firearm, and while there is a reason for this reputation, a lot of us forget exactly why it’s one of the better options. We stock up on the 5.56×45 NATO and the tactical rifles that are chambered for this cartridge, and we can tell you why we believe it’s the best SHTF rifle cartridge out there.
Before we jump into the meat of the article, we do want to point out that there is no one all around, godsend, holy-grail of a cartridge out there. While we have gone with the 5.56×45 round, we are in no way downplaying the effectiveness of other combat rifles or even hunting rifle cartridges. At some point, you just have to make a choice and have the facts to back it up.
Why the 5.56×45
In this article we are going to look at several performance categories and compare the data from five 5.56×45 rounds. Below are five rounds that we have selected for looking at these categories. This is a small sample size for the options that are out there but will give us a look at what this cartridge can do.
- 56×45 NATO Hornady BTHP Superformance Match 75gr
- 56×45 NATO Federal American Eagle FMJ 55gr
- 56×45 NATO Winchester FMJ 55gr
- 56×45 NATO Hornady FMJ Black 62gr
- 56×45 NATO Magtech HPBT 77gr
While having ammo stocked away somewhere might make this section irrelevant for some, the lighter weight of the 5.56×45 NATO compared to other cartridges is important to note.
