The biggest obstacle is usually visibility.
If visibility allows, prone is in our opinion the best position to sight in a rifle.
Then, fall into position behind it.
You really want to focus on a natural alignment to the target.
Your body needs to naturally and comfortably line up with the target.
If you have to fight your alignment while making shots, it will make things more difficult.
You also dont want to be up on your toes.
You want your legs and feet turned out so everything can lie as flat against the ground as possible.
With your feet down, this will help with your mitigation of recoil.
Get the Right Eye Relief
Third, dont let the prone position mess up your eye relief.
However, we suggest you match your grip to the weight of your rifle.
Plus, you might need that grip to manage the recoil.
You may not shoot in it regularly, but now is as good a time as any to start.
In this position, you will be more accurate and waste less time and rounds.
Prone isnt just a position for shooting at the range, either.
The prone position has some serious tactical advantages when in combat situations, too.
