So far all the advise and comments on shooting a mile have been very helpful, we are having a great time trying to hit the steel pig at 1760 yards, so far no luck, with daylight savings time we have time at the end of the day to blaze away with our hunting rifles, and laugh at each other. As Jordan Smith, commented learning the wind has a lot to do with shooting 1 mile, and the wind is making it very interesting. Rio7
