Mk318 vs 5.56 75gr TAP

[vicious_cb]

If barriers are not an issue, which round has better performance against unobstructed targets? Ive heard this mentioned before that Mk318 isnt yaw dependent, if so wouldnt Mk318 be a much better choice than the heavy OTMs since they will be able to fragment at much lower velocities?

[DocGKR]

Let's be clear on exactly what "Not yaw dependent" means; this refers specifically to projectiles that do not suffer from AOA issues or fleet yaw problems as is common with loads such as M193 and M855. Rifle loads that tend not to be yaw dependent include TBBC, Win Bonded, CLUB, Gold Dot, Partition, TSX, SOST, etc...

For unobstructed targets, both the loads specified will likely produce similar results--I would be OK using either one in that situation, although for general purpose use, I'd prefer one of the loads listed in the second paragraph here: https://www.m4carbine.net/showthread.php?t=19881

It seems that most people looking for a non barrier-blind load will be using their rifle in a defensive capacity in, or around their home in heavily populated areas. In these scenarios it would a seem to me that the reduced lethality (vs. Pistol loads, or barrier-blind .223/5.56) of heavy OTM loads after passing through intermediate barriers is an asset rather than a liability.

It would however make sense to keep a barrier-blind load available for special circumstances in marked, or different type/capacity magazines in the event additional penetration is needed.

DOC answered the question, but my question is, how do you know that you won't have any barriers between you and the target?

I wish I had a crystal ball when it come to this stuff, but I don't. So I use barrier blind rounds.

In those situations where intermediate barrier penetration is not a critical requirement, for example LE urban entries

I don't see how home defense differs from an LE urban entry. Most civilians have no need to shoot into vehicles with their AR-15s which is where bonded loads have a distinct advantage over OTMs. I also firmly believe that a fragmenting OTM will cause more soft tissue damage than a bonded bullet that expands, and retains most of its weight. This is critical inside the home where the threat is possibly only feet away.

I am aware of a couple LE entry situations the last several years where fragmenting .223 projectiles failed to incapacitate suspects who were behind walls, furniture, and other cover while shooting at LE officers. In those situations, I suspect barrier blind projectiles would have given officers an advantage at ending the fight...

If I am inside my home and someone is on the outside shooting at me, I will be shooting through glass (FYI).

AR's don't just belong in HD. They can be in your vehicle, property defense, etc.

So it is better to have a bullet that does everything than one that just does somethings.
