If you are unsure, Intro to Long Range is always a good place to start. It is a 2-day course built around teaching you how long range shooting works, what actually matters, and how to start using your rifle, optic, data, and wind calls correctly.
If you want a longer and more complete course, take Long Range Advancement. The first 2 days cover similar foundational material to Intro to Long Range, then the course continues into 2 more days of additional learning, repetitions, positional work, problem-solving, and more advanced training.
If you are running an LPVO, take the LPVO course. The first 2 days are similar in structure to the Intro to Long Range and Long Range Advancement foundation, but the third day shifts into closer-range application so you can learn how to use the optic across distance and up close.
If you are running a scoped carbine or special purpose rifle, take the Scoped Carbine course. This course is built for learning how to apply a magnified carbine across distance, positional shooting, and practical rifle problems while still keeping the rifle in its intended carbine role.
