Please, take your rifle to the range.
Learn how to shoot. Practice shooting (this isn't just the once-a-year sighting in).
Contrary to what I've heard people say, a "pie-plate" group at 100 yards is not good enough. Practice until your groups are inside an inch, two at the most. You owe it to the animals you are hunting. If you can't cut it, don't go out.
Posted from the field where I have had to dispose of/put down a wounded deer for the second week in a row.
Unfortunately, the people reading this aren't my target audience.
