I echo Wogpottor's comment about having someone insert dummy rounds randomly in the magazine (or chamber) while you're shooting live ammo. It's really the best way to detect what you might be doing wrong.
We've used that tactic when training handgun shooters and it's especially useful for the instructor to see what the trainee might be doing wrong.
If I can't be with the rifle I love, I love the rifle I'm with!!
