The Hidden Dangers Of Shooting Your Firearm


Even though we may have never had a negligent discharge, and always follow safe gun handling rules, we may not be as safe as possible when shooting our firearms. I am talking about practicing good hygiene when in contact with your firearms because there are other components of shooting that can be dangerous, over time.

I admit I took absolutely zero hygiene safety precautions during my time in the Marine Corps. Collecting tons of brass on the range and carrying it in my cover (hat for you non-Marines), shooting, cleaning and carrying my M-16 everywhere, and eating my food without the thought of washing my hands.

While we're not likely on week-long field ops or removed from running water, we still don't take the time to practice good hygiene after a day at the range.

Lead Residue:

Shooting a firearm involves an explosion which creates pressures that expel the bullet down the barrel and toward the target. Along with the bullet, gasses push residue from the combustion process back onto the shooter's hands, face, and torso. While this is mostly invisible, it is far from harmless.

The problem with this residue is that it contains lead particles. If you are older than 40 years old chances are good that you grew up playing with toys or lived in homes painted with lead paint.

Lead paint is now prohibited, and unless you ate the paint chips you probably did not suffer ill effects of your exposure to this lead. The lead particles that coat our body while shooting are a different story.

They are microscopic and can easily be absorbed through our skin's pores. Breathing the particles in is another huge way we can contaminate ourselves. Shooting outdoors drastically reduces this method of lead exposure, and this is the reason indoor ranges must have exceptional ventilation in order to be safe.

Ammunition Handling:

Ammunition comes in many different styles. Most bullets are made of pieces of lead. Many manufacturers produce jacketed bullets, which is a coating of metal over of the lead bullet. Breaking it down even further, they could be semi-jacketed or fully-jacketed.

This type of ammunition is generally safer to handle, however safety should obviously be used when using un-jacketed ammunition, where the lead projectile is completely exposed.

Picking Up Brass:

Collecting spent casings is another area where you can unintentionally expose yourself to lead. I oftentimes see children collecting their parents brass after a day at the range. It scares me because a number of times I see their hands go into their mouths without being washed.

The dirt is likely fine lead particles.

Cleaning Your Guns:

Cleaning you handgun exposes your hands to not only the fine coating of lead particles but the sometimes corrosive and unhealthy cleaning solvents.

This is absolutely necessary to do, however, to keep your guns running well when you need them.


What can you do? Shooting your firearm is not exposing you to huge amounts of lead, however, any amount should be avoided if at all possible.

Children and expectant mothers should be especially safeguarded against lead exposure. In addition to thoroughly washing your hands after shooting a firearm, I recommend washing your clothing before hugging or playing with your children.

I wash all my range clothing separately from the rest of the family's laundry, just to make sure I am not transferring lead particles to my daughter's clothing.

I've spoken with doctors about the safety of expectant mothers while shooting. Their advice was that in addition to hand washing, expectant mothers who want to shoot should wear gloves and shoot outdoors.

This will reduce lead exposure drastically. If you are going to eat food, ensure you thoroughly washed your hands after shooting or cleaning your firearm.

It also can't hurt to wear medical gloves while cleaning your guns to keep the lead particles and cleaning solvents off your skin.

Don't freak out —

Chances are, even if you have practiced poor firearms hygiene for years, you have not done irreversible damage to your body. I have 40-plus years of living proof (at least so far). But once my young daughter was born, I changed my habits and now practice good firearms hygiene.

Now you have another way to stay safe on the range. Let's be sure the lead is detrimental to the bad guys, not us.

    Great article!
    Here is another reason I live a hour+ from the outdoor range, so I always carry a pack of wet wipes with us, I work on military bases and when you go thru security they inspect your vehicle and they swab the steering wheel if they find gun powder, they will pull you out of line and it takes a long time to strip the vehicle to make sure there are no weapons in your car, with security with guns drawn. It is not fun and your late for work!

      Hi Scott, glad you liked the article! And great point! I didn’t even think about military bases and traveling on airplanes. gun shot residue on your hands is a surefire way to end up in secondary inspection with TSA (ask me how I know) 🙂 thanks for the great response and point of view!

    Another awesome article, Matthew.

      Good article, it’s important to limit our exposure to toxic substances at all opportunities. Even more so these days as we become unavoidably exposed in ways that weren’t as common years ago.

      One nitpick if I may, there is no explosion during normal shooting, unless there is an obstruction in the barrel or some other malfunction that would cause a catastrophic release of pressure in a unintended direction. Just rapid combustion creating a calculated pressure to propel the projectile down barrel.

      I’m quite sure you understand this, but some readers may not.

    Thanks for the info, Marine. I too never gave hygiene a second thought in the Corps. For me, it was Viet Nam, but the hazards were the same. Really appreciate the heads up on this. Best to you. Semper Fi!

    Knowledge makes for a better safer gun owner. Thank you for sharing me knowledge, though I heard about it a long time back from a certain awesome podcast.

    I have been shooting for over half a century and casting bullets for the same time frame. My blood work is perfect. Not to say there is no danger here, but the risk is being over blown.

    Excellent Article, apart from natural hygiene brought to our attention by this sarscov2.. this is the next eye opener…
    Great stuff
