Beretta A300 Ultima Mossy Oak Bottomland 12-Gauge 3 in Semiautomatic

When the Tennessee gobbler hammers from a foggy hollow at dawn, you need a shotgun that patterns tight and swings fast through the laurel tangles. The Beretta A300 Ultima in Mossy Oak Bottomland is built for exactly that moment—a 12-gauge semi-auto that shoulders naturally and keeps shooting as long as the birds keep coming. Whether you’re working a ridgeline in the Cherokee National Forest or setting decoys along the Tennessee River, this 24-inch barreled turkey gun puts reliable 3-inch payloads where you need them.

What This Product Is and Who It’s For

The Beretta A300 Ultima is a gas-operated semiautomatic shotgun designed primarily for turkey and waterfowl hunters who demand consistent cycling with heavy 3-inch loads. It also serves well for upland bird hunters, predator callers, and shooters who want a durable field gun that won’t beat you up over a long day. This is not a home-defense or competition model—it is purpose-built for hunting scenarios where pattern density and quick follow-up shots matter. The Mossy Oak Bottomland finish makes it appropriate for timber, open fields, and marsh edges where concealment from wary game is critical.

Feature Deep-Dive

The A300 Ultima’s gas system is the same proven self-cleaning piston design found on Beretta’s higher-end A400 models. This means you can run hundreds of shells through it without disassembling the gas assembly for cleaning—a real advantage when you’re hunting multiple days in Tennessee humidity and mud. The piston automatically sheds fouling with each cycle, keeping the action reliable even with heavy 3-inch turkey loads that generate significant residue. This system also reduces felt recoil compared to inertia-driven guns, which matters when you’re shooting a box of magnum shells during patterning sessions.

Beretta’s Kick-Off Plus recoil reduction system is integrated into the buttstock. It uses dual hydraulic dampeners that compress rearward on firing, spreading the recoil impulse over a longer duration. Combined with the gun’s 7.2-pound weight, this makes the A300 Ultima noticeably more comfortable to shoot than many lightweight turkey guns. The synthetic stock also features a raised comb that aligns your eye naturally with the fiber-optic front sight, even with a red-dot optic mounted. The stock comes with spacers to adjust length of pull from 14.25 to 14.75 inches, so you can fit the gun properly to your frame or account for heavy hunting layers.

The 24-inch barrel is specifically chosen for turkey hunting. It provides sufficient length for consistent pattern development with tight chokes while keeping the overall package compact enough to maneuver in a blind or ground setup. The barrel is chrome-lined for corrosion resistance and longevity, and the forcing cone is lengthened to reduce shot deformation for denser patterns. The included Mobilchoke flush tubes allow you to fine-tune your pattern density—many Tennessee turkey hunters will opt for the full choke with 3-inch No. 5 or No. 6 shot for 40-yard lethality.

Mossy Oak Bottomland is one of the most effective camouflage patterns for the varied Tennessee terrain. It blends into hardwood leaf litter, greenbrier thickets, and muddy creek bottoms equally well. The finish is applied over the synthetic stock and forend as well as the aluminum receiver, reducing glare and preventing rust on metal surfaces. The action itself is protected by the same anodized coating used on Beretta’s professional-grade shotguns, so rain or creek crossings won’t cause issues.

The oversized bolt release and bolt handle make gloved-hand operation straightforward. The cross-bolt safety is positioned at the rear of the trigger guard and is ambidextrous in feel, though the release is on the right side. The trigger breaks at a consistent 5.5 to 6.5 pounds with minimal creep—acceptable for a field gun and predictable for shot placement on moving birds. The loading port is beveled for easier thumb loading, and the magazine tube cap is knurled for removal without tools.

Beretta also includes a shim kit for adjusting cast and drop at the comb. This is a feature usually found on guns costing twice as much. By changing the shims between the stock and receiver, you can customize the fit to your shoulder pocket and cheek weld. A properly fitted shotgun swings more naturally and reduces felt recoil further, which translates to better accuracy on live birds.

Ideal Use Cases

• Spring turkey hunting: The 24-inch barrel, tight chokes, and Mossy Oak Bottomland camo make this a primary tool for timber and field gobblers. The gas system handles 3-inch magnum loads reliably for long-range shots.
• Fall turkey and predator calling: Light enough to carry all day, and the Kick-Off Plus pad keeps you comfortable when calling in coyotes or bobcats with heavy shot.
• Waterfowl hunting: With 3-inch shells and appropriate choke, this gun works for ducks and geese over decoys. The camo pattern is effective in marsh and flooded timber.
• Upland birds: Quail and woodcock hunters will appreciate the fast handling and reduced recoil for long walks. Swap to improved cylinder choke for close-rising birds.
• Range patterning: The drilled and tapped receiver accepts a Picatinny rail for red-dot sights, making pattern evaluation at the bench straightforward.

Compatibility Notes

• Ammunition: Accepts all 2.75-inch and 3-inch 12-gauge shells. For best reliability, use shells with 1,200 fps or higher velocity. Avoid light target loads under 1,100 fps until the gun is broken in (approx. 100 rounds of heavy field loads).
• Chokes: Uses standard Beretta/Benelli Mobilchoke pattern tubes. Any aftermarket or OEM Mobilchoke in 12-gauge will fit. Full, modified, and improved cylinder are included.
• Optics: Receiver is drilled and tapped for Beretta-specific mounting bases. Several manufacturers make Picatinny rails that fit without gunsmithing. Red-dot sights, reflex sights, and holographic sights can be mounted.
• Holsters/Slings: Not applicable for holsters. The stock has standard sling swivel studs installed. A wide variety of slings will attach directly.
• Magazines: No aftermarket extended magazines are available for this model. Magazine capacity is fixed at 3 rounds (2+1). The plug is removable for non-migratory bird hunting where legal.
• Cleaning: Standard 12-gauge cleaning kits and bore solvents work. The gas piston should be lightly oiled but not soaked—Beretta recommends minimal lubrication on the piston itself.

Frequently Asked Questions

1. Can you ship this shotgun to my address in Tennessee?
We ship only to licensed Federal Firearms License (FFL) dealers within Tennessee. We cannot ship directly to your home or PO box. After placing your order, you will need to select a receiving FFL dealer in Tennessee. We maintain a list of partner FFLs across the state, or you may provide your own.

2. How does the FFL transfer process work for a Tennessee resident?
Once you place your order, we will contact you to confirm your chosen receiving FFL. We ship the shotgun to that dealer via common carrier. You will then visit the dealer, complete ATF Form 4473, and pass the NICS background check. The dealer will charge a transfer fee (typically $25 to $50). You must be 18 or older for shotgun purchases from a federal firearms licensee.

3. What ammunition works best with the A300 Ultima for turkey hunting?
For Tennessee spring turkeys, 3-inch shells with No. 5 or No. 6 shot in loads from 1.75 to 2 ounces are standard. Brands like Winchester Long Beard, Federal Heavyweight, and Remington Nitro Turkey cycle reliably. Avoid shells under 1,200 fps during the first 100 rounds. Once broken in, the gun will cycle most 2.75-inch field loads.

4. What warranty does Beretta offer on the A300 Ultima?
Beretta provides a limited lifetime warranty to the original purchaser against defects in materials and workmanship. This covers the receiver, barrel, and action components. The synthetic stock and forend are covered for one year. Normal wear items (chokes, springs, o-rings) are not covered. Warranty service is handled through Beretta USA in Accokeek, Maryland.

5. What is your return policy for firearms?
All firearm sales are final due to federal regulations and the transfer process. If your shotgun arrives with a manufacturing defect or damage from shipping, contact us within 48 hours of delivery. We will coordinate with Beretta for warranty repair or replacement. We do not accept returns for fit, cosmetic preference, or change of mind. Inspect the firearm at your FFL before accepting transfer.
