Once my gun is sighted in (1-2" groups @100 yards) then that is the last time before season (unless I drop my gun) that I will shoot from the bench. All my practice is from the standing position at 50, 75, 100 yards. If I can hit a pie plate at 100 yards, I am happy. If I can hit a smaller plate at 75, again happy. And a clay pigeon at 50 yards or less.
I think it's important to practice free standing or kneeling because that is real world.
It is my opinion that bow hunting also helps with muzzy hunting. I slow way down on my one shot. Some years I have tagged out during bow, so that's why I like the challenge of muzzy hunting. One shot, One kill.
