Stonewall, congratulations on your fine new rifle. I recommend getting a marksmanship manual from the USMC or USA. It will show how to perform the shooting positions - standing, kneeling, sitting and prone - properly and provide basics on range estimation, wind drift, use of a sling, etc. Get in the habit early of shooting without a bench - you will not have one in the woods on a deer hunt.
