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".
Why even bother then.....
Buy a box of factory ammo to last you the next half dozen seasons or so, and go bass fishing with all the time and money you saved.
Grandpa's gun is gonna max out at some point, likely a lot less than what could be defined as "precision", but probably a little more than what I would realistically expect from my Marlin levers. I would find out, if only for shi ts and giggles.
