Horses for courses. The work is only worthwhile it its benefits can be realized by the user. For example, the minutiae of brass prep for benchrest or F-class rifles would be largely wasted on still hunting deer ammo for Grandpa's Savage 99 with a 2.5x post reticle scope.
Most with half a lick of sense would realize that, but grandpa's gun is still not a good enough excuse to get sloppy and not find it's full potential. Unless not giving a shi t is your standard operating procedure.
