7.62x51 ammo--Headstamp: LC LR 07--What is it?

[ratski]

Picked out a few rounds from a "bag o bullets"

Headstamp is LC LR 07.
Projo appears to be a small hollowpoint.
Primers are red sealed.

Saw some of this brass listed somewhere but not a lot of info on the actual ammo.

Can anyone enlighten me as to exactly what this ammo is?

Thanks

Dave

Lake City Long Range, with a MK (?) 175 gr BTHP bullet. Good stuff!

The projectile is 175gr Sierra MK. The powder is IMR 4064. The specs call for 41.745 grains (I think they made the switch by 07). The primer is federal GM210M. This is one of the few military loads that we know what is in it.

Long Range = LR. Possibly 175 grain Sierra Match King bullet. Military Match grade.

Correct. Lake city M118LR is the ammo we issue to snipers. It is the 175 smk.

What's the source for that number? I've searched the internet, but my web-fu is weak.
Surely there is no such precision, especially since each grain of 4064 weighs around 0.05 grain.

Thanks for the info.

I had done a bit of research but wasn't sure.

Any idea what this stuff goes for?

Not looking to sell, but obviously it isn't going to be "plinking" ammo.

You are correct there is no such precision, but that is the order. I have a copy of it on my work computer I'll post tomorrow.

FYI: a few years ago I got ahold of 1000 once fired LC LR brass and have been using this load. It is very accurate and consistent. The case is full+ but not compressed.

Awesome, please keep us posted.
