Alex,  For the scoring, they look for an ability to hold good groups.  The requirement is for five of the target faces to have the five shots within the minimum scoring ring. So, if one of the groups has a "flyer" outside the minimum level ring.  It must be shot again, until you have five groups completed. Absolutely yes, on scopes, lazer sights, aperture sights, open sights, etc.  There are no written rules that exclude any time of sights. (for Boy Scout merit badge (Venture does have some restrictions) Same with sand bags, rests, etc. There are no written rules excluding these. Hope you have fun shooting.  More importantly, as you progress with the sport: look to challenge yourself by changing shooting positions and trying different sighting systems.
