when your shooting uspsa steel and they use a formula to figure if your ammo is minor or major power. i know you get more points per target in major but how does that effect you and your qualifying? i know the formula they use and the #'s to make each power bracket.but what does it mean if your ammo doesn't meet the qualifying # for minor? i know you need a power factor 125 to make minor. but according to my figures some of my ammo has a power factor of 117. how will that effect me in uspsa matches.
