A606 is the DODIC for the MK211 (Raufoss) round, in other words they are the same thing. Raufoss refers to where it was made in Norway. It is the round we prefer in our M107's. Pretty cool being able to spot your own impacts on target at over a mile.
What scope are you using that gives you 24 mils of usable adjustment and 10 mils of hold over in the reticle after zero? I'm guessing Marine Corps on this? If so I thought y'all used the 3-12 S&B and it only has 22 mils of total adjustment. Maybe a Horus reticle? Never used that S&B so I'm curious. We are issued a Leupold MK4 4.5-14 with SFP mildot reticle...it works.
