We just received several Vortex Razor HD riflescopes at the store where I work part-time in Louisville. One is a 5-20x50 EBR- 2 MRAD. Right now, I'm displying it on a Remington 700 .338 Lapua. Thing is, I have no experience with the brand. Any here have an impression for this brand or for the benefits of owning the scope I described?
