I posted this eight years ago, but it's worth another shot. 
The top ten reasons to use a scope and shoot F-Class
#10 – You can’t see the front sight anymore.
#9 – It’s too damned hot to put on the sweatshirt and coat.
#8 – Even a Palma rifle is too heavy to hold up long enough to shoot.
#7 – The only thing you can tolerate around your arm is a blood pressure cuff.
#6 – You don’t have to shoot with those smug sling guys anymore.
#5 – You enjoy being treated like a second class citizen.
#4 – Your gunsmith forgot to turn the muzzle end for the sight.
#3 – The occasional scope whack helps keep you awake.
#2 – You can actually see the target when you shoot.
And the #1 reason…
#1 – It looks like some damn fool put an MR-65 center on your LR target.
