I'm 60 and have looked through many brands of scopes over the years. If you can find a used Leupold 3-9 Compact buy it. Even if you have to send back to Leupold and have it rebuilt.
I have one on a Browning Compost Stalker in 7mm-08 and love it. I think I bought it back in the mid 80s. One of the nice things about it besides being compact/light weight is it has somewhat fine cross hairs but not to fine. In the past 8 years I have removed most of my Leupold VXR's (don't like the BDC recitals, to busy, (especially Vortex's) and replaced all of them with the Leupold VX-5HD 2-10 x 42 CDS-ZL2 Firedot. This has got to be one of the best Big Game scopes for the money ever! I also have a VX-5HD 3-15 x 44 CDS ZL2. It's ok with its smaller FOV@100 yrds because its on a 257Wby Mag for Prong Horn so not a lot of trees in the way, otherwise any scope I look at has got to have at least 38yds FOV@100yds, preferably 45yrds or better, also a very generous eye box. Leupold seems to excel at the eye box thing. I have one VX-6HD 1-6x24 on a BLR in 358 Winchester. I don't think the VX-6HD's are worth the big jump in price for what you get. If you want to shave ounces, use a Neoprene scope cover rather than flip up caps. If you know your cartridges path and the substension values of your crosshairs at all powers you don't need the weight of the turrets, zero locks or batteries. However I'd rather go the gym loose 5lbs and not give a hoot about the scope weight. Swarovski is a great scope but they run toward the heavier and longer side. Don't forget Steiner.
