THE POST-HUNT GUN CLEANING ROUTINE

Hunting season has a rhythm to it, and the end of a hunt is where that rhythm falls apart. You get back to the truck after dark, cold through, with wet boots, a tag to deal with and a drive still in front of you. The rifle gets a quick wipe if it is lucky, goes into a case, and ends up in the corner of the garage until somebody remembers it. That is how most rust starts. Not in a dunking or a river crossing, but on an ordinary damp evening when a tired person made a reasonable decision.

The whole routine takes about half an hour, and almost none of it is scrubbing. Most of it is getting water out of places you cannot see, in the right order, before the gun gets shut inside a sealed steel box for nine months. The cleaning is the easy part. The drying is what saves the gun.

Magazine out, action open, chamber checked with your eyes and then with a finger. You already know this. The part people skip after a wet hunt is the next one, which is looking down the barrel from the breech end with a light.

If you set the rifle muzzle-down in snow, laid it in the mud to crawl a fence line, or took a fall with it, there may be something in there. The National Shooting Sports Foundation puts it plainly: even a small bit of mud, snow, excess oil or grease in the bore can cause dangerously high pressures and bulge or burst the barrel. Their advice is to check with a cleaning rod right before you shoot, and NRA Family makes the same point about anything that impedes the bullet on its way out.

Doing it now, at the bench, is better than doing it next November in the dark. Find the problem while you have good light and nothing else to do.

A wet rifle in a soft case is worse than a wet rifle on a table, and it is not close. Speer makes this point in its rifle maintenance guide and adds a number worth remembering: depending on the climate, rust can start forming on metal in as little as six hours. The case does not dry the gun. It holds the water against it.

The second thing is temperature. A rifle that spent the day at 20 degrees and comes straight into a 68-degree living room will sweat, the same way a glass of ice water does, and it will sweat inside the action where you cannot wipe it. Savage Arms recommends letting a firearm come up to room temperature gradually before you case it or work on it. Lay it on an old towel somewhere with moving air and give it an hour. Pour a coffee. Deal with the meat.

Towels get the obvious water. What rusts a gun is the water that is left, and it collects in exactly the same handful of spots every time: the bolt raceways, under the bolt handle, the magazine well and follower, the trigger housing, the sling swivel studs, the recoil pad seam, and the heads of every screw on the rifle. Canned air or a compressor on low pressure removes all of it in about two minutes.

Savage adds a step most people have never heard: back the screws out slightly so trapped moisture can escape, then snug them again once the gun is dry. It feels fussy. It is also where I have found standing water on a rifle I thought was dry an hour earlier.

If the rifle got genuinely soaked, and not just rained on, the stock needs to come off. On most bolt guns that is two action screws. Water sits in the barrel channel and the inletting for weeks, with bare steel on one side and bare wood on the other, and it will not leave on its own. Shooting UK's advice for a drenched gun is the same: separate the metal from the wood, dry them apart, slowly.

Note, pulling the action out of a bedded stock can move your zero, and some rifles want their action screws torqued to a specific number in a specific order. Granted, that is a half-hour at the range to sort out, which is cheap next to a rusted recoil lug. If your rifle is bedded, pillared, or you are not sure, take it to a gunsmith and let them do it once.

Dry patch first. Savage's wet-weather guidance is to run a dry patch through the barrel to pull out water and condensation before anything else, then follow with an oiled patch. Solvent on a wet bore just floats the water around. Get the water out, then clean, then protect.

Push from the breech toward the muzzle whenever the rifle lets you, use a bore guide, and do not let the rod drag across the crown on the way out. The crown is the last quarter inch of rifling the bullet touches, and a dinged one costs you accuracy in a way no amount of cleaning gives back.

As for how hard to scrub: Speer's position is that you do not need to clean the barrel after every outing and are better off leaving it alone during the season, saving the real cleaning for season's end, heavy shooting, or moisture exposure. Their end-of-season routine is solvent patches with a bronze brush, brushing breech to muzzle at least ten passes and up to twenty if it has been neglected, then patches until they come out mostly clean, then dry.

I am in the clean-less-than-you-think camp on accuracy barrels, and I will argue about carbon fouling with anybody. That said, water is not carbon. Water comes out the same day, every time, no exceptions. And whenever you do scrub a barrel properly, confirm zero at the range before you hunt it again.

Pull the bolt all the way out. Wipe the body, the lugs and the face, and put a light film of oil on the lugs and the cocking cam. Go easy inside the firing pin channel, because heavy oil in there thickens in cold weather and can slow the pin enough to cause a misfire on the one morning you cannot afford it. Dry and sparse beats wet and generous.

The trigger group gets air and nothing else, unless the manufacturer says otherwise. Shotgun hunters, take the choke tube out. It is the single most ignored part on a duck gun, and the threads underneath hold water and salt all season. Clean the threads, put a light coat of grease on them, and run it back in so it is not seized in there next fall.

Magazines come out and get emptied, which Speer recommends anyway so the spring is not sitting under tension for nine months. Leave the sling off and hang it to dry somewhere else. Wet nylon or leather strapped against steel is one of the better rust machines you can build by accident.

Last, wipe every outside surface with an oiled or silicone cloth, including the places your hands actually live. Skin leaves salt and acid behind, and on a blued rifle you can read somebody's fingerprints in the etching a year later.

For an ordinary wet hunt, the NRA's American Hunter says a good gun oil or CLP is enough, and I agree. For guns that take real abuse, they point to products that leave a wax-type film behind after the solvent flashes off, naming Birchwood Casey Barricade, formerly sold as Sheath, and Outers Metal Seal. Those are worth having if you hunt coastal or marsh country.

Speaking of which: if you hunted salt or brackish water, American Hunter's first instruction is to flush the gun with plenty of fresh water as soon as you are off the water, because fresh water is the only thing that actually removes salt. Dry it, then protect it. Rinsing a gun feels wrong the first time you do it. Salt left on steel is worse.

Scopes get forgotten because they look fine. Wipe the tube, the rings and the bases, brush the dust off the glass before you touch it with anything, and finish with lens wipes rather than your shirttail, which is sandpaper as far as a coated lens is concerned. Speer notes those wipes run under $15. While you are up there, check that your ring and base screws are still tight, because a season of recoil and a truck bed loosen things.

Then dry the gear the gun has to live with. Turn the case inside out or stand it open, hang the scope covers, and dry the ammo. Wipe the cartridges down and let the box dry out rather than stuffing damp shells back in a pouch. Put a dry gun into a damp case and by morning you have a wet gun again.

Granted, this is the part everyone skips, and skipping it is survivable. It is also the cheapest ten minutes in the routine.

A safe does not dry anything. It is a sealed steel box, and it will faithfully hold whatever air you close the door on, which is why a gun put away damp in December is a gun with freckles in March. Everything above is really just the work of making sure the air you shut in there is dry.

Inside, the target is roughly 30 to 50 percent relative humidity, and a cheap digital hygrometer on a shelf will tell you where you actually are instead of where you assume you are. If the number runs high, you need a dehumidifier, and there are only two kinds that matter. A 12-inch electric rod at $38 warms the air just enough that moisture stops condensing on cold steel, and it mounts low so the warm air rises through everything. A silica gel box at $23 needs no power at all, holds 450 grams of desiccant good for about 37 cubic feet, and goes back to work after a stint in the kitchen oven once the indicator changes color. If your safe has a pre-drilled cord hole and an outlet nearby, use the rod. If it does not, use the gel. In the Gulf states or a basement, use both. I wrote the long version of that in our dehumidifier guide, including how to size one for your interior.

A few storage habits finish the job. Guns go in bare, not in soft cases or holsters, which trap moisture against the metal exactly the way the case in your truck did. Leave an inch or two between them so damp pockets of air cannot sit still; if yours are packed shoulder to shoulder, the honest answer is that the safe is too small. And go light on the oil, because over months the excess runs downhill into the stock wood and the trigger group, and neither is improved by it.

Check the hygrometer and the desiccant color once a month. It takes ten seconds and it is the only way you find out the rod came unplugged in February.

Most of us have, so here is the recovery. Light surface rust, the orange haze that wipes partly off on your thumb, usually comes up with oil and patience. Soak it with gun oil, give it twenty minutes, and work it with a patch first. If that is not enough, move to bronze wool, and only then to very fine steel wool, always with oil as the carrier and always with light pressure.

Know the cost before you start. American Hunter is blunt about it: rust on bluing cannot be removed without damage, and fine steel wool with oil may take the rust off but will thin or remove the bluing with it. Test on a spot that does not show, like under the barrel ahead of the fore-end, before you touch the side of a receiver.

If you can feel the rust with a fingernail, it has pitted, and that is past the point where a patch and some oil fix it. That is a gunsmith conversation about refinishing, and the same goes for rust inside a bolt body or anywhere in the trigger group. I am comfortable working on the outside of a rifle. I am not a gunsmith, and I do not do my own trigger work.

For a stock that swelled or went cloudy, dry it slowly in a normal room over several days, not near heat, and then rub in a little stock oil once it is fully dry. The finish usually comes back further than you expect.

That is the routine. Half an hour at the bench on the night you least feel like it, and the rifle comes out of the safe next fall looking exactly the way it went in. If you have a step you swear by that I left out, I would genuinely like to hear it. Mostly, though, I would like you to not put it away wet.
