Who's running a Leupold Mk6 1-6 w/ CMR-W 7.62 reticle AND shooting 168gr. factory AMAX or FGMM SMK? I'm considering purchasing one of these scopes in the near future and I was just wondering how well the BDC does in matching up with these rounds? I know it's calibrated for 175gr. @ 2575, so considering either AMAX or FGMM at 168gr will leave a SCAR barrel with a muzzle velocity of around 2470 I'm a tad concerned the BDC will be useless.
