With long range shooting and factory ammo you are going to restrict youself. Handloading is almost a must as there are few factory loads that are using "heavy for caliber" or VLD bullets needed to obtain the high BC's which are very helpful to flatten trajectories,buck the wind and decrease travel time. Not saying it cant be done with factory fodderbut you are going to need all the accuracy that can be squeezed out of a rifle/ammo combo. For the serious shooters they even have the throat cut for a particular bullet. Not to rain on your parade just giving you an opinion.
