Hi a friend gave me a visor Shilba-Master Hunter with a magnification range 3-9x40B, and I wanted to ask, what it can hunt with a rifle in my viewfinder Shilba Remington 700 Winchester Magnum from 338?, I have also a Bushnell Elite 3200 with the same increases and bell I will use a rifle Ceska the 375 H & H.
