A man who's had some confrontation experience knows that when it's for real, you mostly miss men, with a rifle, at 50 yds, much less 500 yds, cause it's at night, or they are using cover, and firing BACK.
What real life rifle confrontations have you had? Most dope dealers don't pack long arms. How do you know it's night? How do you know about cover? Your scenario's are made up by you and you think that's the only way they will happen. What if a good bolt man spot's your hidey hole and plink's you coming out to take a dump?
