What does this mean? Are you still reloading or have you stopped?
AAC 5.56 77gr Matchking OR their house brand 77gr to very well. 2750fps from my 18" Mk12... on par with Mk262
Black Hills red box 5.56 77gr OTM is not identical to MK262 Mod 1 anymore.....it now uses a Hornady 77gr bullet instead of the SMK.
The change to the Hornady bullet was around this time last year. It's performance is VERY similar. Very doubtful the average shooter and likely even a very good shooter would be able to see any difference.
Where did you read / see this ?... specifically the Hornady bullet part .
Here's the only thing I was able to locate on it, website is "KIR Ammo" - scroll to the bottom and they mention the Hornady 77g bullet being used in the ammo..Never heard of them, know nothing about them or their business-just found them in a Google search. Also can't locate a separate listing for Hornady's 77g OTM...Found plenty of websites selling Sierra's, Nosler's, Lapua's and Berger's but not Hornady's 77g OTM.
Ok... I'd bet the linked upper description is a snafu.
You're welcome...could very well be but that is literally the only reference on-line I can find and nothing on the 77g Hornady projectile...If I cared enough, I'd call black hills on Monday to ask but it's not that critical for me since I don't rely on factory ammo for anything...My clone of Mk262 Mod 1 flies just like the real thing, literally within .1mil ele drop at 700-800m and .75-1.00 MOA out of my Mk12 Mod 1 (1.5-3MOA at 100m on avg out of my carbines w/ non magnified optics) and I use all the same components, except the powder (mine uses AA2520 while Black Hills uses a non-cannister grade powder, AFAIK).
The mod1c still uses the SMK The commercial package 5.56 OTM uses the Hornady bullet. Give a call and confirm it 605 348 5150
I will phone them on Monday.
You might want to check out the IMI Razor Core 77gr OTM, it's a popular alternative to the MK262, known for its consistent accuracy.
Razor core has been more accurate and had better Es sd than bh mk262 for me
Velocity is within 10 fps out of a 20” saturn for me 2791 for bh mk262. 2780 for razorcore
Berger has amazing factory loads. Both 73gr and 77gr flavors. But they’re only loaded to .223 pressures, not 5.56.
that sucks. I figured that would happen so bought. 5000 of their TMK
18”. Short action customs. Not sure blank prolly Bartlien ?
I've had to do the same but the 75 ELD-M is a good replacement, just a higher price point.
I certainly would load it with a recipe to follow. How many grains N140 are you using....same COL as the MK262?
Razor core has been more accurate and better numbers for me than black hills lately
Thanks. Similiar to my Varget koads...a little lighter.
No idea…just shoot it on the move and shoot range; almost never beyond 100 yards, and most inside 50. I think it’s a good analog to 262 for training.
Ever try N150? I've been using it for my bolt .223 with Hornady 75 BTHPs and the same charge weight I use with N140 (24.7) gives me about 75fps faster (than with N140) and no pressure. This isn't loaded to AR mag length but I've been meaning to work up a load at AR mag length so I can use it interchangeably in my bolt and gas guns.
