Why I didn't like 5.56 when I was in the Army...
1. Having grown up with .30-06 deer rifles...the M16A2 felt like a Nerf toy.
2. 5.56/.223 is illegal for deer in at least 48 states...Adult Whitetail deer & adult humans tend to weigh about the same (90-350 pounds).
3. Having seen a deer get up and run away from a .270 thru the lungs didn't give me any confidence in the 5.56's performance.
4. It is a step up from .22WMR, but most definitely a step down from .308/7.62
5. Pencil-thin barrel means POI changes as it heats up...sometimes drastically.
6. The M60E3 was WAY more fun
7. Yep, it'll kill a Panamanian (or anyone else) stone dead if you hit 'em in the right spots...but when that bunghole is shooting at ya with an AK,
you ain't that precise because you are trying to find cover to shoot from...its a matter of Center Mass...instead of precision shooting.
In the case of center mass...I want Big Freekin Holes in the Other Guy that he can't get back up from...
screw that 5.56 "wounding is more logistically important" crap...what is important to me is bringing the Squad home alive & well.
And that's why I didn't like 5.56
Of course now, I like it as a lightweight coyote killer...which is about the biggest critter its useful on...or legal on.
And my retired Marine Wifey...likes it because she's had 2 right shoulder rebuild surgeries, and the low recoil is handle-able.
5.56/.223 is also a much better home defense round than .22LR or 9mm, so hey, it ain't all bad...
So the Wifey will whip out her Hello Kitty AR-15...and I'll whip out my Camo AR-10, and we'll both be happy putting holes in Bad Guys.
We'll let the ME decide who killed which BG with what round first
