Today I bought a new Savage Trophy Hunter XP in 308. It came with a Nikon Prostaff BDC 3-9X40. In the safe I have a Nikon Prostaff 5 2.5-10X40 & a older Leupold VX-II 3-9X40. The Prostaff 5 was intended to go on my varminter AR. I had thought about putting the Leupold on my Marlin 336 30-30. Now I'm thinking about putting the 3-9 from the Savage onto the AR & the Prostaff 5 or the Leupold on the .308 and whatever is left on the Marlin. Or not. What says you all?
