I've been looking around trying to a find a scope under 20oz for a lightweight setup. I see two frequently mentioned for this: the Leupold VX-5HD and the Swarovski z5. However, both have many reports of tracking issues either with wandering from vertical zero, being off 1/2MOA or more on horizontal dialing, returning to zero, or any combination of the above. Are there any out there that are durable and reliable in tracking, similar to Nightforce? I could get a Nighforce NX8 2.5-20 but it's 28oz (and FFP where I'm sure SFP would work fine for hunting) and if I can drop 1/2lb through a lightweight scope I'd prefer it. Any recommendations?
