You could go to the Nikon site and compare numbers... but I think they are pretty close. I actually do not know because I use Bushnell Elites 3200 with a Ballistic Reticule. The Omega is suppose to be set for a ML shooting 200 yardswith a 250 grain Shockwave and 150 grains of powder.
PM Cayugad he uses Nikons and knows them fairly well.
