Unless one is already familiar with firearms, it is necessary to start with a basic firearm safety course. Many State Game and Fishing Commissions will provide this training course for a relatively minor fee. This course may be required before being allowed to obtain a hunting license.
For those already accustomed to firearm safety and use, it may be necessary to contact local gun clubs in the area to find others of similar interest. Gun clubs can usually recommend the best instructors for all types of shooting, including long range marksmanship.
