USMC BDC Turret

[gbernardski]

Picked up a bdc turret that is for a S&B and M118LR ammo. Does anyone have an idea of the conditions this bdc was set for, altitude/temp etc?
Thanks!

A complete guess here, but I'd assume it's U.S. Army Standard Metro which is 59 deg. F, 14.503 psia, and 78 % R.H.

I don't know. My guess is based on if they went with a standard atmosphere at all, it would probably be U.S. Army Standard Metro vs. ICAO. It's not based on any prior knowledge of other BDC turrets.

Gotcha, thanks. That had me input my muzzle velocity, altitude, humidity, and bullet grain. Then they made me a dual. I asked for the blanket Mark 4 data for the M24 and they acted like they didn't know what I was talking about. Nightforce has a kickass velocity reticle program.

Sorry for the SLIGHT drift. Thanks.

Continuing the "spin drift" here a second: GW, were you ever able to get an M24 turret for the Mark 4?

I'll see how that compares to what I get once I try it.
Thanks!
