Give us young bucks a minute to catch up. You know where your guys are, because you know the direction of march. You can likely see the man in front of you, and the one behind, but that is all. All of a sudden, automatic weapons fire is shredding the jungle around you. Leaves and vines are falling like rain, dirt is kicking up all around you, and you spot the tell-tale muzzle flash of an AK through the veil of green. Are you going to carefully line up your irons sights, and wait for a distinct helmet actually camouflaged perfectly with foliage, and quite possibly dug in to appear while you slowly squeeze the trigger like you learned on the range?
Or are you going to dump a magazine and hope for the best? Me too. The lethality out of a inch barrel was fantastic, and 5. While some diehards would still never accept 5. But when we started chopping the barrel down to As far back as the Battle of Mogadishu, if you look carefully enough, you can find reports of 5. Above a certain velocity threshold, the bullet positively comes apart in tissue. This is well known, and backed up by research from giants such as Dr.
Martin Fackler, founder and head of the Wound Ballistics Laboratory. But, velocity threshold is the key point here. And 5. In the last 20 years, ballistics have done a lot for improving the round. And even among troops that have options about what to carry, the debate still rages of 5.
But so do a monster truck and Prius. My point is that both are old, and maybe it is time to evolve. And therefore, 6. How would, in a hypothetical shoot off, commercial 6. Overall, it would seem to be a pretty good compromise. With barrel, bolt, and magazine changes, it fits in the standard M While it does get crushed at long range compared to 7. While it does weigh slightly more than 5.
While on paper, a specialized 5. Now we move into one of the main pros of the 6. Dual purpose to me is something that can be used for more than one task, and perform those tasks well. For our purposes here, both and 6. There is lethality in the 6. That lethality increases when the barrels are shorter. This also makes it an excellent home defense, or CQC firearm, in terms of maneuverability. In terms of hunting, the 6. These are animals like feral hogs, antelope, white, and black tail deer.
There are plenty of instances where hunters have taken smaller black bears and even elk with this rifle cartridge, but I would advise against using 6. And, as with anything, bullet choice is key, as is your shot placement and distance. Moving back into another con of the 6. Overall, the 6.
In fact, when compared with other similar AR cartridges like 5. Ammunition cost is one of the biggest factors for people not training with their chosen firearms because it directly correlates with how often you go to the range.
But as of right now, it is certainly not the most affordable AR round. Certainly nowhere near as many people shoot 6. Next we move on to another pro in the form of felt recoil.
Now, I do want to make a disclaimer here. The felt recoil of the 6. Therefore, you can shoot a much bigger caliber that may cause your recoil to feel the same or similar to a smaller one just based on the weight alone. I found this out several years ago when shooting a different caliber of rifle in my old Henry Lever Action. I found that a cartridge with a grain bullet recoiled harder into my shoulder than the cartridge with the grain bullet did. So how heavy is the recoil on the 6.
As we mentioned a moment ago, each shooter, each gun, and each specific cartridge is going to be different. Though, I would consider it to be closer in feeling to the chambered AR.
Now moving on to our final fact, we come to some of the confusion regarding this cartridge. As we already briefly discussed, back in when Remington got approval from SAAMI, the original cartridges had to be down-loaded, pressure wise.
The reason why is because the chambers of the Remington rifles had a poor design that led to pressure spikes. The reason why this happened is basically because Remington wanted to get the round tested and in the hands of the military, but ended up rushing the process before everything was even actually tested properly by them. I do want to say that the SPC II is an updated chamber design, not necessarily a change in the ammo itself. The 5. Another cartridge under consideration was.
The Remington in civilian disguise has the same profile as the 5. You can shoot. Anyway, this all occurred in The current 5. It fired a grain steel-cored bullet to pass the NATO required to penetrate helmets at long range.
This from a machine gun. Lethality in soft tissue was never addressed. Terminal effectiveness lethality depends on striking velocity, yaw or fragmentation to cause soft tissue damage.
