What bullet is right for me?

[TShooter]

I have been shooting long range for some time using a .243 and a 6mm REM with good success. The club I shoot at has a LV and HV class and I wanted to shoot both so I have re-barreled my 6mmREM to a 6BR. The barrel is a Krieger 33" with 8 twist. I shoot the Lapua 105 moly for the HV but do not have a feel for bullets of 70gr or less that is required for the LV.

What would you suggest for a bullet of 70gr or less when I have to shoot from 100 to 400 yards? I prefer moly coated bullets to extend my barrel life. Also what load would you recommend?

TIA
