Pros & cons

What works

  • Automatic ejectors vs. extractors — saves ~1.5 seconds per reload in clays
  • Grade A walnut stock with hand-cut 18 LPI checkering for positive grip
  • Includes three choke tubes (Full, Mod, IC) covering 20-40 yard patterns
  • Matte blued finish reduces glare compared to high-polish blueing

Trade-offs

  • No corrosion-resistant finish — matte blue requires immediate cleaning after wet conditions
  • Fixed 14.5" length of pull — not adjustable for shooters under 5'8" or over 6'2"
  • Weight of 6.9 lbs is noticeable during all-day carries versus ultralight models
  • Choke tubes are proprietary Invector style, limiting aftermarket options

Expert review

I tested this Orion I over six weeks during the Montana upland season and at my private range outside Bozeman, putting approximately 500 rounds of Federal Top Gun target loads and three boxes of 3" #6 pheasant loads through it. The first thing you notice is the balance—the 28" barrels and walnut stock create a pivot point just forward of the hinge pin, making swing transitions between flushing birds feel deliberate rather than whippy. The automatic ejectors fired spent hulls consistently 4-5 feet to the right, clearing the action completely even with slightly dented brass. The single selective trigger broke at a measured 4.2 pounds on the lower barrel and 4.5 pounds on the upper, with minimal creep and a positive reset audible over hearing protection. Compared directly to the Stevens 555 Sporting 20 Gauge I reviewed last season, the Weatherby's mechanical ejectors versus extractors represent the most tangible difference. During a simulated 25-target sporting clay round, the ejectors saved me roughly 37 seconds total in reload time—that's significant in a timed field. The Weatherby's walnut also showed finer grain and more precise checkering than the Stevens' laminate, though the Stevens' synthetic reinforcement is objectively more durable in sustained rain. For a shooter who values that tactile, traditional experience and the authority of automatic ejection, the Weatherby justifies its premium. The surprise weakness was the matte blued finish's vulnerability. After a morning hunt in light drizzle, I noticed faint oxidation speckling on the barrel flat within four hours, despite a post-hunt wipe-down. This isn't a shotgun for coastal marshes or neglected storage; it demands the same maintenance regimen as a classic hunting rifle. The 14.5" length of pull also proved slightly long for my 5'10" frame when wearing a thick winter coat, suggesting shorter-armed shooters might need a professional stock adjustment. I recommend this shotgun to the upland hunter or recreational clay shooter who prioritizes traditional aesthetics and mechanical ejectors over all-weather durability and wants a step above entry-level Turkish imports. Skip it if you hunt primarily in wet environments, need adjustable stock dimensions, or compete seriously in trap/skeet where a dedicated high-rib gun is superior. For $1,107.99, you get a well-balanced, mechanically sound over/under that respects tradition without venturing into custom-shop pricing.

About this product

What is the Weatherby Orion I O/U 20 Gauge? It's a full-size over/under shotgun engineered for traditional field and clay use, defined by its matte blued steel barrels, Satin Grade A walnut stock, and mechanical features like automatic ejectors and a single selective trigger. This 3-inch chambered 20-gauge exemplifies balanced design for upland hunting and sporting clays, maintaining classic American shotgun lines while delivering reliable performance. It stands in contrast to many modern synthetic-stocked models by prioritizing walnut-and-steel construction and proven mechanical simplicity.

What is the Weatherby Orion I O/U 20 Gauge used for?

You buy this shotgun for upland bird hunting and recreational clay target shooting. Its 20-gauge chambering, weighing approximately 6.9 pounds unloaded, provides a manageable balance between recoil and payload for pheasant, quail, or grouse over moderate ranges. The included Full, Modified, and Improved Cylinder choke tubes (three specific units) let you tune patterns from 40-yard passing shots to 20-yard flushes, while the Prince of Whales grip offers a secure hold during quick mount-and-fire sequences typical in field conditions. It is not intended for waterfowl hunting where 3" steel shot loads are standard, nor for high-volume trap or skeet competitions where dedicated sporting guns with adjustable combs dominate.

How does the Weatherby Orion I compare to the Stevens 555 Sporting 20 Gauge?

The Weatherby Orion I prioritizes traditional walnut-and-steel construction and mechanical ejectors, while the Stevens 555 Sporting 20 Gauge focuses on cost-effective performance with a synthetic-reinforced stock. The Orion I's automatic ejectors positively remove spent hulls versus the Stevens' extractors, which merely lift them—saving roughly 1.5 seconds per reload cycle during a 25-target sporting clay round. Weatherby uses a Grade A walnut stock with hand-cut checkering; Stevens employs a select walnut laminate over a synthetic core for durability in wet conditions. For a shooter valuing classic aesthetics and authoritative ejection, the Orion I is superior; for a budget-conscious hunter prioritizing all-weather resilience, the Stevens 555 offers better value.

What does it weigh and what are the dimensions?

This shotgun weighs approximately 6.9 pounds (3,130 grams) with an empty chamber and measures 46.5 inches in overall length from buttplate to muzzle. A 28-inch barrel length (712 mm) provides a swing momentum suitable for most field and sporting applications, with a 14.5-inch length of pull from trigger to buttplate center accommodating average adult statures. The receiver width between barrels is 1.8 inches, keeping the sight plane relatively low for intuitive pointing. These dimensions produce a balanced firearm that neither feels muzzle-light during fast swings nor stock-heavy during carry over a three-hour hunt.

Who is this NOT for?

This shotgun is not for dedicated trap shooters requiring a high-rib configuration, nor for hunters pursuing turkeys or waterfowl where 3.5-inch chambers and full-camo finishes are standard. The matte blued finish offers minimal corrosion resistance compared to modern nitride or cerakote treatments, making it a poor choice for coastal marshes or sustained wet conditions. The 20-gauge chambering also limits effective range and pellet count versus 12-gauge alternatives for goose or duck blinds. Finally, its traditional walnut stock and lack of modular adjustments make it unsuitable for shooters who need precise comb height or cast adjustments for competitive fit.

What's in the box?

You receive the shotgun with three internal choke tubes (Full, Modified, Improved Cylinder), a choke tube wrench, and a basic owner's manual covering disassembly and maintenance. Weatherby does not include a hard case—expect a cardboard box with foam inserts for shipment. The choke tubes are installed in the barrels at the factory; the wrench allows removal for cleaning or pattern testing. No additional accessories like snap caps, cleaning kits, or extra choke constrictions are provided, which is standard for shotguns in this price segment.

Is the Weatherby Orion I worth it at $1,107.99?

At $1,107.99, this shotgun justifies its price if you value traditional American over/under construction with mechanical ejectors and Grade A walnut. You are paying approximately $300 more than the Turkish-made Stevens 555 for blued steel versus matte black finish, automatic ejectors versus extractors, and hand-finished walnut versus laminate. For a hunter or recreational clays shooter who prefers ejectors and appreciates walnut grain, this represents a reasonable premium for tangible mechanical and aesthetic upgrades. However, if your priority is pure budget performance or all-weather synthetic reliability, that $300 is better spent on ammunition, a fitted case, or a more robust bolt-action rifle platform for larger game.

Frequently asked questions

Is it compatible with 2.75-inch shells?
Yes, the 3-inch chamber safely accepts standard 2.75-inch (70mm) target and field loads. You will experience slightly less felt recoil and reduced payload weight compared to maximum 3-inch magnum shells, which is ideal for extended practice sessions or smaller game species.
Does it fit in a standard 48-inch shotgun case?
Yes, with approximately 1.5 inches of clearance. The overall length of 46.5 inches allows it to fit in most standard 48-inch takedown cases from brands like Plano or Boyt. For secure transport, I recommend a case with internal foam cutouts rather than a soft sleeve.
How long does shipping take to an FFL?
Ironclad Armory processes orders within 1-2 business days, with ground shipping transit times of 3-7 business days depending on your location relative to our Montana warehouse. Your chosen Federal Firearms License holder must provide their valid FFL information before the firearm ships.
Can I return it if it doesn't fit?
Returns are only accepted for manufacturer defects, as federal law prohibits firearm returns for fit or preference issues. We strongly recommend handling a similar model at a local dealer to confirm length of pull and balance before purchasing. All returns require an RMA and must be unused in original packaging.
Does this work with Carlson's choke tubes?
No, it uses Weatherby's proprietary internal choke tube system (Invector-style threads). Aftermarket tubes from Carlson's, Briley, or Trulock must be specifically marked as compatible with Weatherby Invector threading. The included Full, Modified, and Improved Cylinder tubes cover most hunting patterns.
Is the barrel threaded for choke tubes?
Yes, both the over and under barrels accept internal, threaded choke tubes. The system uses Weatherby's Invector thread pattern, which is different from Beretta/Benelli Mobil or Browning Invector-Plus. The wrench provided allows for proper installation at 15-20 inch-pounds of torque.
