I shoot to 600m regularly with my short barrelled 308 Tikka completely stock with a 3-18 VX6 and it works
also do same with my 6.5TCU M700, 7-35Mk5 and it works also, it also worked with 2-10 VX5.
Both guns shoot magic MOA or better neither one is a PRS Style as it were.
Both I have used for actual game shooting
Target is 8 inch plate so slightly bigger than MOA size.
Use what you have for a start, you may be surprised what it can do.
