In my opinion the cheapest route would be ...
Used anschutz 54 in good shape can be found for 1k these days with not too much trouble
25 MOA rail from DIP products
Burris signature rings with inserts
SWFA 10x
Ammo will be A big factor but that’s where you can experiment quite a bit at shorter ranges. What your rifle likes best may surprise you.
This, plus what others said.
Downside of a traditional Anschutz for long range is the lack of an adjustable comb on most models.
The new Bergara .22 might be worth a look.
