The only 77gr .223 in the Black Hills Amunition online cataloge is the SMK.
Does anyone know why the OTM isn't in the catalog?

Re: Black Hills 77gr OTM not in the catalog
I am 99% sure that is the same thing. A SMK is an OTM bullet.

Yes, except the OTM SMK has a cannelure. Maybe loaded hotter too?

Re: Black Hills 77gr OTM not in the catalog
I have the 77gr SMK new production and it is cannalured. I plan on calling Black Hills tomorrow and ask if the OTM is still available.

Re: Black Hills 77gr OTM not in the catalog
The OTM is pretty new. It is loaded to 5.56 specs, not .223. It is identical to the MK262.

BLUF: OTM = HPBT Match
The "open tip match" (OTM) designation is a legal description used by DOD JAG to argue for the use of these bullets in combat. The Geneva and Hague Conventions have strict prohibitions against projectiles from causing "unnecessary suffering." The argument at the time stated two major issues in the use of OTM:
1. These bullets perform similiarly (in ballistic gellatin) to full metal jacket bullets already in use.
2. These bullets are more accurate, thus reducing "collateral damage" (hitting non-combatants).
JAG was successful in getting these OTM bullets and ammunition approved for combat use. It can be found in both 5.56 (Mk262)and 7.62 (M118 LR) NATO ammunition.
OTM is a more accurate description, and helps to prevent confusion that can occur when the designation "hollow point boat tail" is used. Match bullets (Sierra in this discussion) have an open tip as a consequence of bullet manufacturing processes, but there is an air space in front of the lead core within the copper jacket. A true hollow point bullet (as typically found in hunting bullets or self-defense handgun bullets) has a cavity within the lead core. This encourages the bullet to expand when it hits a fluid or solid object. This type of bullet is absolutely prohibited for use in combat.
The Mk 262 Mod 0 was loaded (typically) with the Sierra 77 grain MatchKing bullet. During full auto fire, and when suppressors were used, bullet set back occured. This resulted in the Mk 262 Mod 1, which used the cannelured bullet, reducing the occurance of bullet set back.
I hope that this helps.

If you are looking for OTM, Kevin at HCS sounds most likely has some.

One additional Note -- briefly the 77gr Nosler was used in the Mod1 as Sierra was resistant to the Cannelure.
As Longebow stated the OTM is BTHP.
I get Mk262 from BH, I also get Red and Blue box 77gr -- same bullet, don't sweat it.

So are the OTM (Mk262) and the Red box exactly the same, and the Blue box differs only in the brass being once fired?

No. Red and blue box are .223. OTM and MK262 are 5.56. The 5.56 rounds give you about an extra 100 feet per second.

Thanks. I figured the OTM was hotter, but didn't think about the .223-5.56 difference.

Re: Black Hills 77gr OTM not in the catalog
Thanks guys,
That sounds like the load I use to duplicate that is about right. I use 25.5 gr. of RE-15 behind the 75 Hornady or 77 gr. Sie./Nos CC. and get 2690 from a 16" barrel. 5.56 chamber.
Are your chambers 5.56 or .223? Or a variation of the .223?

Re: Black Hills 77gr OTM not in the catalog
I've shot the mod 0 and mod 1 in full auto suppressed m4a1's the mod 0 in my experience did not like to feed well out of GI mags and I witnessed a catastrophic failure in 130 degree heat good thing for 203's or the gun would have been worthless. I feel the mod 1 is more reliable as of current. But that was only 1 round of mod 0 so I by no means am trying to cast distaste on the mod 0.

Re: Black Hills 77gr OTM not in the catalog
BTT.
There is some good info on the difference between the 223 77 and 556 77 here. I am getting this question more and more as people are looking for the 556 77 stuff.
For a while they were loaded with different bullets. Now all Black Hills 77 bullets are the Sierra 77 SMK with cannelure, as used in the Mk262 mod 1.
Here are the listed specs:
223 2750fps from a 24" barrel
556 2750fps from a 20" barrel
I dont think you will find a difference in accuracy, unless you have one of "those" rifles that just insists on puking out the good stuff.
Just remember not to shoot 556 ammo out of a 223 chamber.
http://www.triadtactical.com/Black-Hills-New-5.56mm-77gr-Sierra-OTM.html
BTW, Black Hills now also offers the 69 Sierra in 556 as well.

Re: Black Hills 77gr OTM not in the catalog
We are seeing about a 50-60fps increase over the .223 77SMK in a 20" RRA at 850MSL in 65 degree weather. I chronoed some (the red box 77 OTM) a couple of weeks ago and it averaged 2650 and change. This barrel has always been a little on the slow side, and has about 300 rounds through it.
This is my wifes rifle, and she's been out to 650 yards with it so far.
Give Triad a call and get you some.
