I think I have three of the NF SHV 563's. the 3-10, non-illum, moar, parallax adjustable. i have one shv 4-14x56, one 4-16 husky and one 3-12 husky.
My absolute favorite scope is the 3-10 shv. 20ish ounces, about like the 4-16 husky. Yes the husky's have more magnification, but i've had no problem shooting out to 600 with the 10x scopes. That little F'er is bombproof.
IMO the eye box is more forgiving in the shv than the husky's, which can make a difference in an awkward hunting shooting position.
I'm kind of in the same boat OP, I have a new 6.5-284 wrapping up with my builder and I need glass for it....but do i go for another 4-16 husky or a smaller shv. I am budgetarily limited to about $1k, and i try to pick up the c563s whenever i see them used, since they're discontinued. I'd love to see a 4-12x42 SHV in that 20oz range hit the market.
