MCH,
Relax and stay off that knee..the poster probably has pointing down to an exact science..they just place a finger real close to their nose and point..natural move, with a little practice..

Then you line up those bumps on the barrel; take a fine aim on the target and hit the trigger. You have this big pattern and a lot of shot taking care of the hitting....

This crap isn’t hard. 😉

laissez les bons temps rouler
