Does anyone have good Standard Deviations for M852 or M118LR? Lot numbers would be a little too much to ask for.

I'm just interested!

Hi Carl;

Have some general info on the M852;

Bullet wghts; 167.8 to 168.2
Powder wghts; 42.3 to 42.8
Concentricity; .001 to .005

Straightness; .001 to .005

Velocity deviation +/- 18 fps

Group deviation slightly more than 1 moa at
500, to 6 1/2 moa at 1000

Hope this helps with your question sorry no lot numbers, and the info is generic.

take care Carl...Jim

Jim,
Thanks for the info!
Years ago when I was shooting "leg matches" to become "Distingushed" I tested some M852 and M118 so that I could load comparable practice ammo. That test data is long gone!

Take care!

Carl
