Does anyone know how to range using the new Redfield Revolution 4-12 with the Accu-Range reticule?
What are the subtension and at what power?
I read somewhere that the subtensions are the same as the Leupold LR reticle. Leupold would be the one's to call on this, since they're marketing the Redfield line now. It's not a problem rangefinding with it really, once the subtensions at any given distance are known. Look here for an explanation on how to apply a ballistic reticle for rangefinding--
