The Leupold VX-2 has worked good, and reliably for me. My choice was the 2-7 CDS, which i purchased for $350 including a free engraved dial for my hunting load. It appear the 3-9 CDS is the same price. Using the 2-7 on a muzzle loader, i somehow managed to smuck a milk jug filled with water over 1/4 mile away, with one shot. Myself, i like them CDS dial, yes i do.
My favorite scope is a VX-3,,, 2.5-8, but after equipping it with the CDS dial, and a wide duplex reticle, it cost considerable more.
