Novice to world champ
The Hawke sounds interesting but do you want to spend £800 on an untested scope? Top end shooters using big nikkos have won just about every comp there is, from world titles to GP series. They are tried and tested proven winners, be patient and get a second hand mk2. £350-£400 with bells and knobs and your money back if it's not for you.
Nearly every shooter goes through the same situation of trying several scopes and rifles before they settle on the one for them , some shooters never stop changing kit. When you are at millride next ask a few of the shooters if you can have a look through their scopes, you will soon see why your night eater cost you a few targets on Sunday .
