Sight in six weeks early, not the night before

Do it now. Not the weekend before opener, when every public range within an hour is full and the only box of your load left on the shelf is a different bullet weight.

Sighting in early buys you the one thing you can't manufacture in October: time to fix what you find. A loose base, a scope that won't track, a barrel that's copper-fouled into throwing fliers, an ammo shortage. Every one of those is a solvable problem in August and a season-ender in November.

A rifle that printed one-inch groups last year has spent eleven months in a safe, a truck, and somebody's hands. It hasn't stayed the same. Assume nothing.

Check the screws before you burn a single round

Most "my scope won't hold zero" problems aren't scope problems. They're mounting problems, and they're free to rule out at the kitchen table.

Pull the rifle out. Put a proper fitting bit or a torque driver on the action screws, the base screws, and the ring caps. Not a multitool. A screwdriver bit that fills the slot completely, because a chewed-up screw head is a problem you'll be living with for years.

Use the torque numbers the ring and base manufacturer prints in the instructions. They vary by maker and by material, and "tight" is not a specification. Overtightening ring caps can dent a scope tube. Undertightening lets the whole thing creep under recoil, a few thousandths at a time, until your group walks off the paper and you blame the ammunition.

While you're there, check the stock for cracks at the recoil lug, make sure the barrel is still free-floated if it's meant to be, and confirm the scope's turret caps aren't quietly seized.

Buy the ammunition in quantity, from one lot

Pick one load. Then buy enough of it for sighting in, for practice, and for the season, all at once, and check that the lot numbers on the boxes match where you can.

Different bullet weights from the same manufacturer will land in different places. So will the same bullet from a different production run, sometimes noticeably. Sighting in with the cheap stuff and hunting with the premium stuff is a genuinely common mistake, and it's how a rifle that "shoots great" puts a bullet six inches off at 200 yards.

Budget somewhere around two boxes for the whole process. One to get zeroed and confirmed, one to practice with from field positions. If your rifle's zero is already close, you'll use less.

Start at 25 yards and save yourself a box

Bore sight first. On a bolt gun, pull the bolt, rest the rifle solidly, look down the bore at a target 25 yards out, then move the reticle to the same spot without moving the rifle. On anything you can't see through, a laser bore sighter does the same job.

Then shoot three rounds at 25 yards. Adjust to bring the group to the point of aim, or slightly low depending on what you're planning at distance. Now move the target to 100.

Skipping the 25-yard step is how people spend forty rounds hunting for a hole in a target backer.

Three shots, then let it cool

Fire three, then set the rifle down with the action open and wait. Five to ten minutes, longer on a thin sporter barrel in warm weather.

A hot barrel doesn't shoot where a cold one does. String five or ten rounds fast and you'll watch the group climb or wander, and you'll adjust the scope to chase a condition you'll never see in the field. You get one shot at an animal from a cold, clean-ish barrel. That's the shot you're trying to learn.

Adjust in whole clicks and trust the math. If your turrets move a quarter inch per click at 100 yards and you're two inches low, that's eight clicks up. Make the correction, shoot another three, verify. Don't adjust off a single shot. Ever.

Choose the zero on purpose

For most hunting east of the Mississippi, a 100-yard zero is honest and easy to think about. You know where the bullet is at the distances you shoot, and you're not doing arithmetic in the cold.

A 200-yard zero flattens the useful range for open country, at the cost of your bullet running a little high at 100. Decide which one fits the ground you actually hunt, not the ground in the magazine photo.

Whatever you pick, write it on a piece of tape inside the rifle case along with the load, the bullet weight, and the date. In fourteen months you won't remember, and your memory will be confidently wrong.

Then get off the bench

A bench, sandbags and a level target tell you what the rifle and the ammunition can do. They tell you almost nothing about what you can do.

Once you're zeroed, shoot the rest of the box from the positions you'll really use. Kneeling. Sitting with a sling. Off a pack. Braced against a tree with your off hand as padding. Out of a treestand harness if that's your season, and from the seated, twisted, awkward angle that stands really involve.

Your groups will open up. That's the point. The distance at which you can keep every shot inside a fist-sized circle from a realistic field position is your maximum ethical range, and it's almost always shorter than the range your rifle is capable of. Respect the smaller number. A clean kill is the whole job.

Confirm again after the drive

Rifles get dropped, leaned, jammed behind a seat, and bounced down two hours of forest road. Any of those can move a zero.

If you travel to hunt, plan to confirm at camp before you hunt. Three rounds at a safe backstop, from a stable rest, at a known distance. Many outfitters and camps expect it and have a spot set up. Know before you go whether shooting to confirm is permitted where you're headed, because it isn't everywhere.

Know the rules where you're standing

Regulations on where and how you can discharge a firearm vary enormously by state, province, county and even by parcel. Distance-from-dwelling rules, caliber restrictions, shot-size and ammunition restrictions, hunter orange requirements, and rules about sighting in on public land are all local, and they change.

Some jurisdictions restrict or ban lead ammunition in certain areas, often to protect scavenging birds. Copper monolithics shoot well and expand reliably, but they're a different load, which means a different zero. Switch in August, not in camp.

Check your current regulations digest every single year. Last year's booklet is decoration. If you're unsure whether a spot is legal to shoot on, ask the agency or the landowner in writing rather than guessing.

The habit that separates the two kinds of hunters

Some men show up at the range in late October with a rifle they haven't touched since last season, shoot one round, say "close enough," and go hunting.

The other kind confirms cold, from field positions, with the same ammunition they'll carry, and knows their own limit to the yard.

Both of them will eventually get an opportunity at an animal at last light with a heartbeat they can feel in their hands. Only one of them has already earned the right to take it.
