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?
Bout 100k of .22 lr, a peice of land away from anyone else, some crops to grow, a big garden. A couple places to get water. Enough sons and brothers to make anyone who tries to steal from you a living nightmare. A river or place to set a trought line.
HAHAHAHAHA!
Mk262 will easily defeat a filled magazine and give good result on the other side.
Right now though, the barrier blind ammo as recommended by DocGKR seem to be the best overall performers: https://www.m4carbine.net/showthread.php?t=19881
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.
I personally have defensive use mags loaded with Speer GDHP 5.56MM 55 and 64 grain loads, and Federal LE223T3. The Speer GDHP 5.56 64GR is whats in my home defense AR. All are recommend loads from Doc.
For back up stash I have IMI M193 since I can’t afford to keep thousands of rounds around of GDHP and especially not LE223T3.
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.
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.
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.
