I have just become aware of PRS but know little to nothing about it. I did see that they have different divisions for different guns and different classifications for shooters depending on how well you shoot throughout the year. What I really haven't seen is the format. Are they shooting steel or paper or a mix of both. I have heard that the matches start at 1000 yards. Is this true? I will have more questions about guns and gear later but for now I would just like to know about course of fire and targets including sizes.
