For those asking, it is for a light 6mmBR crow gun currently successful out to 700 yards.
Why do do so many people think that shooting at longer distances needs large scopes with higher magnification? Drop increases faster than the square of the distance so vertical dispersion does too. WInd deflection goes up more than linearly with distance. Image bluring from atmospheric scintillation goes up more than linearly with distance and that is not helped by higher magnification and hurt by larger objective lenses. I agree that 20x is plenty at 800 yards. It's plenty at a mile and beyond too. More magnification is only helpful if you're eyesight has less than normal resolution. Too much power severely hurts target acquisition time and that's bad for hunting. I consider the 36x and up scopes as strictly for benchrest targe shooiting.
You didn't say what you want to spend.
Arguably the "best" scope made which meets your specs is the US Optics ST-22. It's 22 power with a 44 mm objective. Only $1580 (compare it to some other US Optics scopes) Many reticle options are available They also make the 17x44 ST-17. Same but lower power and costs more.
I use (and really like) the Leupold 16x40 Mk 4 M1 for long range shooting. (anything over 500 yards) I't's available with mil-dot, target dot, and duplex reticles. Sometimes on sale for around $1100. It has 140 moa elevation adjustment range.
SWFA used to sell a 20x40 model of their "Super Sniper" Mil dot. It was decent quality and around $400. Apparently SWFA has discontinued it. You might find a used one.
Leupold used to make a 24x40 benchrest socpe, They may still make the 25x40 FX-3 "silhouette" scope. I don't know much about it, Neither has much elevation and windage adjustment.
I don' know of much else between 16 and 36 power. Apparently fixed scopes haven't sold well.
4x, 6x and 10x are still plentiful as are 36x.
