Are you shooting indoors or out? I have never had problems shooting outdoors. Indoors, I've found that a head shot is usually a ricochet off the shooting bench side wall. Moving up or back a half-step will usually change the impact of the empty, sending it out on the range or down your neighbor's neck. Either way, you're good!!
Added advice to Gen-X shooters (you baby-boomers already know this): for a hat to help in this situation, you have to wear it with the cap in front. Hope this helps.
