I've trying to find my first LR deer rig. Looks like a Savage 112BVSS 7mm Rem (1-9.5"). According to my calculations, the 162 gr. A-Max @ 3100 fps (26") can reach out to 750 yards and stay above 2000 fps. At what velocity will this bullet expand at? I'm looking for 1000 yard reach for hunting shots. Velocity at that range is 1730 fps. Is that enough speed to get some blowup on a rib shot?
