This.
No actual twist rate will stabilize a bullet in flesh.
Yaw makes a difference and is barrel dependent, but I think thats more of an m855 thing.
I chronographed M193 55 FMJ through my issued 16" carbine. Average Velocity was 2965 fps at 15 feet from the muzzle. M193 was also considerably more accurate at 100 yards than the 55g JSP we were issued at work. After reviewing two shooting reports where M193 was used to stop a suspect, I decided it was good enough for defensive ammunition in my personal carbine.
That’s why I don’t get the M193 obsession. Sure, if you only had a 1:12 twist or only had M193 available (or if it was 1969) then I can see the argument. But in 2020 there are faster twists as standard production and MUCH better bullet choices, most of them being heavier. M193 is great for plinking or training so you don’t shoot up your good stuff, but for real-world applications today? Not so much.
Both M855A1 and Mk318 utilize fragmentation as part of their wounding mechanism. However, both also have a core that penetrates beyond the fragging (unlike M193). Best of both worlds?
I’m not limited to mil issue ammo. Those who are don’t get to choose.
I haven’t seen the price and availability on those make me want to compare performance vs the LE stuff that is.
I think a basic load in mags x2 of premium ammo should come first.
Then I’m not concerned with stacked deep ammo not being premium. In fact I like it to also be for training, so M193 fits.

That 62 TSX is a great load.
The M193 obsession comes down to two things:
-
It’s cheap. For the same reason people buy off-brand, low quality guns and claim that you’re “just paying for the name” with the high quality weapons, they want to think the same thing about ammo.
-
It offends the core sensibility that technology is NEVER the answer. The answer always needs to be “Shot placement. Train more and make your shots count and it won’t matter kind of bullets you’re using…”
Have you gotten your hands on the new Black Hills/Lehigh ammo? I dont care much for Lehigh products but maybe Black Hills did some tweaking I am not aware of.
Yes, it does look impressive. I would note, however, that it was fired from a 20" barrel where the other two were fired from a 14.5" and a 16" barrel.
Less difference than you’d think between the 20 and 16, and more evident through barriers than bare gel. Pub velocity for the load pictured (.223) is 3025 from a 24". Velocity from one of my 16" is ~2770. I use the 5.56 variant, which is ~100fps faster and even better.
I have a box en route.
Projectile is 62gr CCCu from Lehigh, untweaked.
I like the 193.
In fact, I love the 193. It’s what I learned to shoot with in basic way back in 1981. The biggest portion of my ammo stash… you guessed it, 193. Here’s why. It’s cheap, it’s reliable, it’s easily available, and it’ll get the job done.
Is it my duty ammo? Nope. Not any more. It’s a good back up plan if need be, but I use it to train with. We train more than we fight, so that’s the type of ammo we need the most of anyway… right? Why the 193? Because it’s cheap, it’s reliable, it’s easily available, and it’ll get the job done.
However, there are much better rounds to select from these days to use as a defensive round. Sure, they cost a bit more, but everything is a bit more these days, and just like I learned in the Army, service ammo is more expensive that training ammo… Only difference is that 193 doesn’t come outta the box painted blue.
My bolt gun uses the Fed 62gr tactical bonded. It’s a good round, and more important, it’s what the gun likes. This isn’t a combat carbine. This is a precision rifle, and though shot placement ALWAYS counts, with this weapon, it’s paramount.
My ARs use either the Hornady 75gr TAP, or the IMI 77gr OTM LR MOD 1. I may have to go to some other easier to find rounds to build up my duty ammo supply, but for now, this is what I’ve been going with.
I also have a quantity of PMC Bronze 55gr FMJ for training ammo. It’s even cheaper than the 193. It also has noticeably less recoil, so is most likely a much weaker round. (it’s .223, not 5.56 for one thing)
I will add this… If the SHTF, EOTWAWKI, Boogaloo, what ever they call it these days comes, and I run out of everything but the 193… I’ll still by a dangerous old man.
Providing I make it that long.
Is that also a Black Hills load?
I taxed this from another website. User “LEID” was the shooter.
“Exit wound @75yds. with 5.56MM 62GR. CCCu from a 10.5” w can"-LEID
No bones were hit.
Yes. The 62 TSX is available in both a .223 and 5.56 load.
I bought 200 rounds of it last night. Yikes! It ain’t cheap, that’s for sure.
Wonder if Black Hills uses a CFE-type powder with these copper TSX bullets?
Interesting results. I always found Lehigh designs to be gimmicky. Does this offer anything that Mk318 doesn’t already do?
They do not. This said, I’ve shot lots of black hills tsx, and have friends that have too. Noone has seen a copper issue.
Reliable 100% petal separation down to 1500fps in ordnance gel. I’m not sure about mk318, but doubt its anywhere near this. Also, allegedly much more accurate.
MK318 will frag down 1500 FPS or even lower. It’s accurate. 1.5 for the MK318 Mod 1. It is a great load. Any of the loads just mentioned are awesome though.
