If you know your gun and the loads, the most accurate is always best. We ALL wiggle and shake! If the best you can get from a rest at 50 yards is 10" and then add in wiggle off hand, just what can you hit?
Take groups to 1" at 50 and even a 10" wobble can take a deer but don't expect a deer at 100.
Unless all animals are shot from a rest how does ANYONE consider poor groups "good enough?"
You that think 3" is good from a revolver at 50 yards would turn inside out with the same from a rifle at 100.
There is NOTHING GOOD ENOUGH!
