I agree there is too much argument for argument sake.

With 12ft/lbs rifles the only thing that delivers, matters, is perfect shot placement. Be that hunting or competitions.
All the calibres require doing a drop chart.
The higher the velocity the flatter the shooting, and longer the Point Blank range.
Few people can equal a laser rangefinder for judging range.
Beyond 20m then rangefinding gets really tricky.
No calibre has the smack power to compensate for poor shot placement.

Getting all the calibres to shoot well is shooting time. Whats not to love? "Best" is making a perfect shot placement. Easiest at the longer ranges is the .177. All take real application to hit tiny every time.
