In 2011 I was practicing where I would hunt before the opening and could see I was good to 500 yards, but could not get confidence at 600y.
In 2012 with a different rifle I was good to 400y.
In 2013 I was good to 500 again, and I was right on when I got my buck at 477 yards.
Someday I would like to be good to 600 yards. I keep building new rifles and buying new equipment.
There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self. -Ernest Hemingway The man who makes no mistakes does not usually make anything.-- Edward John Phelps
