Changing Your Browning Citori Choke for Clay Shooting
A Browning Citori can perform impressively across trap, skeet, and sporting clays, but the right choke tube helps determine how efficiently the shot pattern reaches the target. Changing the constriction allows you to adapt the shotgun to target distance, speed, and presentation.
Before working on the shotgun, treat it as loaded until you personally verify otherwise. Keep the muzzle pointed in a safe direction, open the action, remove all ammunition from the gun and surrounding area, and inspect both chambers and the barrel ends. Choke work is simple when performed carefully, but it should never be rushed.
Your Citori may use Browning Invector, Invector-Plus, or another factory-specified choke system. The tubes can look similar while having different dimensions, so confirm the exact system in the owner’s manual or on the barrel markings before selecting replacements.
Prepare The Shotgun Safely
Set the unloaded shotgun on a stable, padded surface with the action open. If the Citori has removable ejectors or other parts that could be stressed by awkward handling, support the gun so it does not rock while you work. Good lighting makes it easier to see the tube slots and inspect the threads.
Use a choke wrench that matches the tube style. A properly fitted wrench reduces the chance of damaging the slots, while a thin layer of high-quality choke-tube lubricant helps prevent the tube from binding in the barrel. Avoid ordinary grease unless it is specifically suitable for firearm choke threads and the temperatures involved.
Do not attempt to remove a tube immediately after firing. Barrels and tubes can become hot, and heat may make lubricant run or increase the risk of burns. Allow the shotgun to cool completely before beginning.
Identify The Correct Tube System
Look at the markings on the barrel or consult the Citori manual to determine whether your shotgun uses Invector, Invector-Plus, or a model-specific system. Standard and extended tubes are often designed for particular bore dimensions, and a tube that appears to fit may still be unsafe if its profile or thread pattern is wrong.
Chokes are commonly marked by names, symbols, or degrees of constriction. Cylinder has little or no constriction, improved cylinder is slightly tighter, modified is tighter still, and full provides the greatest constriction among these common choices. Sporting-clay shooters may also use skeet, improved modified, or specialty extended tubes.
The upper and lower barrels may carry different chokes from the factory. Note which tube is installed in each barrel before removal, especially if you are testing a combination that has already produced useful patterns.
Remove And Install The Choke Tube
Insert the wrench fully into the tube’s slots and turn counterclockwise when viewed from the muzzle. Use steady pressure rather than sudden force. If the tube will not move, stop and have a qualified gunsmith examine it; forcing a seized tube can damage the barrel threads or deform the wrench slots.
Once removed, clean the exposed internal threads with a suitable cloth or soft brush. Check the old tube for flattened threads, dents, galling, or lead and carbon buildup. Inspect the barrel’s internal threads as well. Damaged threads should be assessed by a gunsmith before another tube is installed.
Apply a light coat of choke-tube lubricant to the replacement tube’s threads, keeping lubricant away from the bore. Start the tube by hand and turn it clockwise until it seats smoothly. Finish with the wrench using firm, moderate pressure. The tube should sit flush or at its intended position; never fire the Citori with a tube that is cross-threaded, loose, or missing.
| Clay discipline | Common starting point | Why it can work |
|---|---|---|
| Skeet | Skeet or improved cylinder | Broad patterns suit close, crossing targets |
| Trap singles | Improved modified or modified | Supports longer, rising targets |
| Sporting clays | Improved cylinder to modified | Flexible for changing stations |
| Trap handicap | Modified to full | Helps maintain density at greater distance |
| Close rabbit or teal presentations | Cylinder to improved cylinder | Limits excessive constriction at short range |
Match Constriction To The Course
Skeet targets are generally close and fast, so a more open pattern such as skeet or improved cylinder is often a practical starting point. A tight choke can make a quick target harder to hit because small aiming errors are less forgiving. The best choice still depends on the station, ammunition, and the target’s actual distance.
Sporting clays require more adaptation. A course may include a close incomer followed by a long outgoing target, making improved cylinder in one barrel and modified in the other a useful baseline. If your Citori has a single selective trigger, decide which barrel will fire first and place the more open choke in that barrel when appropriate.
For trap, targets usually move away from the shooter, so modified, improved modified, or full may be considered. However, a tight choke is not automatically better. Pattern density matters, and an overly tight pattern can punish small errors. Test the setup on paper before settling on a competition combination.
Pattern And Inspect Before Shooting
Patterning verifies what the choke and load actually do together. At a safe range, fire several shots at a large paper target from the distance typical of your clay discipline. Mark each shot separately, then examine pellet distribution, density, and gaps rather than judging only the outer spread.
Use the same shell type you expect to shoot during practice or competition. Shot size, velocity, wad design, and payload can change the pattern considerably. If the pattern is uneven or unexpectedly tight, try another choke-and-load combination and record the results.
After the first few shots with a newly installed tube, confirm that it remains secure only after the gun is unloaded and cool. A loose tube can damage the muzzle and may create a dangerous obstruction. Regularly checking tightness is especially important with extended tubes that receive frequent handling.
Protect The Citori Between Sessions
Remove and clean choke tubes periodically instead of leaving them untouched for months. Moisture, fouling, and residue can encourage corrosion or make removal difficult. Wipe the threads clean, apply fresh choke lubricant, and reinstall the tube snugly.
Store spare tubes in a labeled case so that Invector and Invector-Plus components do not get mixed. Record the constriction installed in each barrel, the shell used, and the patterning results. This simple log makes it easier to repeat a successful setup at the next clay session.
When cleaning the exterior, use products compatible with the Citori’s finish. Owners of coated models can review guidance on Dura-Touch finish before choosing solvents or protective products, particularly around textured or treated surfaces.
A Practical Choke-Selection Checklist
- Confirm the Citori’s exact choke-tube system before purchasing or installing a tube.
- Begin with improved cylinder and modified as versatile sporting-clay options.
- Pattern every new choke-and-load combination at a realistic distance.
- Keep the action open and verify an empty chamber before touching the tubes.
- Inspect, lubricate, and periodically retighten tubes according to the manufacturer’s guidance.
A carefully fitted choke gives your Browning Citori a more predictable pattern and lets you tailor the shotgun to each clay presentation. Work slowly, verify every component, and consult a qualified gunsmith whenever a tube or barrel thread shows damage. Then take your tested setup to the range and build your station-by-station plan around the patterns you can trust.
