I'm going to need to get some mounts and rings for my 300 rum build soon. Will be used for moderate long range hunting(500-600 yards) and am not quite sure what to get. Will be going with a leupold vx3 4.5 x 14 x 40. Was thinking about an egw one piece base for ease of mounting the scope on the long action. Not sure which rings or what height. With that base lows should fit?
