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.
I disagree to a certain extent. If I am hunting at modest ranges with something like the rifle/scope mentioned above, using a hunting bullet of my choosing, and I'm getting the accuracy I deem necessary for the use, I'm not sure that searching out additional precision is always a good use of my time. I'm also not likely to put my pocket pistol in a Ransom Rest and burn through $200 of defensive ammo to see what shoots best at 50yds. Good enough can be good enough. It's not necessarily "not giving a shi t".
