Gun courses are a great way to start. Locate a public range to shoot at, pick up a couple of boxes of 130 & 140 GR bullets in a couple of different makes, Rem, Win, Federal, ect. Take you time at the range, with the target at 25yds away and see where your new gun prints using the lowest power on the scope. Make necessary adjustments to move the bullet point of impact to 12 position and 2" high. Move the target out to 100 yds and repeat your shots and scope adjustment until your are 1" high 12 position. Your rifle will tell you which bullet and weight it likes best by the smallest group fired. I like to fire 2 shot groups while zeroing in the rifle then a 3 shot group as a final group. Congrats on the first!
