Researching the best choice for a 5.56 defensive cartridge I found most recommend barrier blind rounds that don't fragment. It seems that a trade off exists between barrier penetration and effectiveness, but assuming you are only hitting unarmoured targets at the required velocities, wouldn't the fragmenting M193 style bullet be desired? I'd choose increased lethality normally over increased lethality in the slim chance I shoot them behind a barrier.
Bump because at least this isn't another bait thread

Yes, that was the original concept. The xm193 would destroy soft tissue, but could not penetrate barriers well. As we moved to shorter barrels and longer engagment ranges we created a new projectile, the m855. The m855 is 62gr vs. 55gr and has a mild steel core. The weight allows it to carry more energy for longer distances, at the trade off of doing less damage to soft tissue, but you do get greater barrier penetration as well.
M193 is good all around. Reliable fragmentation with a 14.5 out to 100 yards and will break up after going through 1-2 house drywall with insulation.
75-77 grain otm and tmk do the same in regard to the wall, but have they're effective fragmentation range out to around 300 or so due to the bullet design.
Barrier blind loads, mainly soft points give good expansion and good penetration through barriers like walls, auto glass and light metal.
Either is fine, just be aware that if thsee are being used indoors, the barrier blind has a higher chance of passing through more walls.

>Either is fine
But wouldn't the fragmenting options be far more effective, assuming it works as intended? The chance to hit a vital organ is massively improved.
M193 is a perfectly valid option. Any 5.56 is going to be horrendously killy at home defense range though.

I understand that, but I'm wondering why it is people recommend expanding rounds that seem far less effective.
B-bump
If you anticipate contact at near ranges, a reliably expanding bullet is preferred over a maybe fragmenting one. M193 fragments nice past 100 yards. Inside 100? Maybe. That's all. It's a nasty little round. It's a matter of where you expect contact. Barrier penetrating rounds are only useful at penetrating barriers that you can observe bad guys behind. Which, most likely, will be inside of a couple of hundred yards anyway. If I know I'm getting into a dust up mostly from 10-250 yards, I want heavy TSX/T3/etc. If I know it's likely a 100-500 yard shin dig, I want 262 or 193. But, that's just me. As all around flyswatter, ain't nothing wrong with M193.

because at close range 855 and similar rounds will poke a hole straight through without tumbling or fragmenting. they are all going to act differently depending on your barrel length and twist too.

is that a rifle grenade?
