Just bought a remingtion tm sps 700 308 and had the Leupold VX11 4x12x40 #57000 installed at my gun store. I was told that for tarage shooting only, I should of went 4x18x50. Is this true ? The range down here is 100 yards. I would thing 100 to 300 yd. should be ok with this scope. If anyone has this scope- let me know-- Marty D.
