The height of your rifle’s cheek piece is a vital factor in successful shooting, but it’s particularly relevant with springers, because a perfect head position allows you to relax properly into your stance. When you’re relaxed, you’re comfortable, and you avoid the build- up of muscle tension. Tension is the enemy of the springer shooter, due to the inconsistency of hold it promotes. Never forget, if ANYTHING changes in the way you handle your springer from shot to shot, its point of impact is likely to change with it. Get your head in the right position - even if it means customising your rifle’s cheek piece - so your sighting eye can line up naturally with the scope. The rest of your stance will flow from there.
