What type of 5.56 round for a WROL situation.

[.Scarecrow.]

A lot of these rounds would be nice if I had time to reload. Or if I could even find them.

[Fail-Safe]

Okay, and is 50 grains really enough? Not doubting you, I even think 55 grain is light. But I honestly don't know. I'll check those rounds out. Is it required for bullets to fragment for them to do a lot of damage? I have heard Fragmentation is not everything.

The 50gr TSX is an all copper bullet, and while it is light in weight, because it is all copper it is longer (has more mass) than traditional 50gr bullet. Its length (mass) may be that of 60gr bullet of normal construction.

Mass = weight


Volume= the amount of space an object takes up



What you meant to say was that because its made with a lighter density bullet it would have the same/similar volume as a heavier bullet made with denser materials.

Huge fan of the 50gr TSX load. I fired some into milk-jugs. It penetrated about the same as a 9mm 124gr GDHP through water/milk-jugs.

People have shot many creatures with the X bullets over time and love them.

Here is picture>

The 3 slugs I recovered (inches):
1: 0.512 x 0.306 = 0.409 avg
2: 0.511 x 0.344 = 0.4275 avg
3: 0.518 x 0.295 = 0.4065 avg

Since it's in the LE .308 thread this might have been overlooked;

but Doc posted pictures of gel test shots through AK mags by various rounds.

The 77gr OTM ain't looking so good in that pic. Just sayin.

I am not sure about the Mk262 77 gr because a guy on another forum had a good point about if (God forbid) you were to face someone with a chest rig that with rifle mags. A round that would penetrate that and still be effective. He said the 77 gr HP probably won't have enough penetration. What are your thoughts?

Could this guy have been talking about a plate carrier? Two to the chest, one to the head. If you recognize body armor right away, well then, center mass of the head.

6" of penetration directly into the heart/lungs with that kind of frag pattern will readily drop a dude. I'm not chest thumping here, but I've seen me do it.
The projectile will get through and cause significant damage. Of course, it can be improved upon, and it isn't what I would consider optimal, which is why I recommended going with one of the recommended loads in DocGKR's thread, in which he makes it pretty clear that the best balance of performance from a 5.56 gun is one of the barrier blind rounds.

Never BTDT, but from a medical prospective, even my most obese patients don't have more than 1-2" of fat over the sternum (I'm talking 500#+ people), and if you want to count pecs (most obese people don't have much pec anyway), you MIGHT! encounter 3" or so, but it won't be dense.

The major unknown is the sternum/ribs.

Some people have a serious sternum, some don't.

I will NOT! volunteer to be shot while wearing a chest-rig with AK mags in it with 77gr OTM even if someone promises to aim for a mag. 12-14" of penetration is to account for marginal hits/hits from less than ideal angles. You don't need 12-14" of penetration on a sternal front-on shot to mess up darn near everything.

Bottom line.. 55gr, 62gr, in a WROL situation what you want is accurate placement and lots of it.

I'm a fan of the SOST stuff. Nasty fragmentation with the bonus ability to penetrate after encountering an intermediate like a car-door or windshield.
