scopes optics

Looking for an optic for long range hunting that won't break the bank (under $1000) but will also get the job done. Looking for something with exposed turrets, FFP, and a magnification somewhere in the 2-24 range, open to suggestions. Ideally something with a reticle that is a christmas tree...

I have a nf 5.5 22 x50 30 mm tube scope mounted on a tikka t3x it has about an 1/8 inch of clearance using nf rings .885/low I am replacing it with a nf atacr 7 35x56 its a34 mm tube my ? is what scope height rings do I need to get the new scope to fit hope fully as close as possable thank you don
