Long Range Shooting
A better option? A range bag that can be carried in one hand or over the shoulder, holding a shooter's most commonly-needed gear items plus a few pieces for emergencies, is ideal for long-range shooters.
For the long-range shooter at practice or competition, the first item, no doubt, is your mobile device loaded with a free long-range shooting app. Add in a notebook and writing instruments, and you are all set to calculate and record your day's shooting.
Safety is always on the mind of the shooter, so that means hearing protection and shooting glasses should also be found in your bag.
A small medical kit is a real plus to have on hand, too, and for worst-case scenarios, a tourniquet is a great idea that takes up very little room. But, make sure you know how to use it before loading it into your bag. During a high-stress situation is not the time to try to figure out a tourniquet!
Ammo, yes, whatever ammunition you think you might need should definitely be in your bag.
Of course, long-range means knowing the distance is of extreme importance, so a range finder and a spotting scope or higher-magnification binoculars are a must.
