Tikka T3x 150-Grain .308 Winchester Rifle
Our Tikka T3x in .308 Winchester represents Finnish precision engineering at its finest. This bolt-action rifle is optimized for 150-grain ammunition, delivering consistent sub-MOA accuracy whether you’re hunting medium game or engaging targets at the range.
The T3x features our signature cold-hammer-forged barrel, a crisp single-stage trigger adjustable from 2-4 pounds, and a modular synthetic stock designed for all-weather performance. We’ve equipped this rifle with a steel recoil lug and widened ejection port for reliable cycling in any condition.
- Cold-hammer-forged 22.4-inch barrel optimized for 150-grain .308 loads
- Sub-MOA accuracy guarantee at 100 yards with quality ammunition
- Adjustable trigger (2-4 lbs) with metallic bolt shroud
- Modular synthetic stock with interchangeable pistol grips
- Detachable 3-round magazine (10-round available separately)
Barrel design and .308 Winchester performance
Our cold-hammer-forging process creates a barrel that delivers exceptional accuracy with 150-grain factory loads and handloads alike. The 22.4-inch barrel length provides optimal velocity for .308 Winchester cartridges while maintaining balance and maneuverability in the field.
The 1:11 twist rate stabilizes bullet weights from 147 to 168 grains, though the rifle truly shines with 150-grain projectiles for deer, hog, and medium game hunting. We’ve free-floated the barrel from the synthetic forend to eliminate pressure points that can affect accuracy.
Bolt action and trigger system
Smooth bolt operation
The T3x bolt features a 70-degree throw with three locking lugs that distribute pressure evenly across the bolt face. We’ve machined the bolt body from a single piece of steel and added a metallic bolt shroud for enhanced weather resistance.
Our mechanical ejector provides positive case extraction even in adverse conditions. The widened ejection port allows spent brass to clear cleanly without interference, reducing the chance of a stovepipe malfunction during rapid follow-up shots.
Modular stock system and ergonomics
Our T3x synthetic stock is engineered for versatility across hunting and shooting disciplines. The modular design allows you to swap pistol grip inserts to customize the grip angle for your hand size and shooting style.
We’ve designed the stock with a wide forend that provides a stable platform for bipod mounting and offhand shooting. The checkered grip panels and forend ensure positive control in wet or cold conditions when gloves are necessary.

What people are saying
Common questions about the Tikka T3x .308
Our T3x .308 features a 1:11 twist rate that stabilizes bullet weights from 147 to 168 grains effectively. The rifle performs exceptionally well with 150-grain ammunition, which provides an ideal balance of velocity, trajectory, and terminal performance for deer-sized game.
Many hunters and shooters report their tightest groups with 150-grain loads, though the rifle will shoot heavier bullets accurately as well. For long-range target shooting beyond 500 yards, 168-grain match bullets take advantage of higher ballistic coefficients.
We recommend a brief break-in procedure to achieve optimal accuracy from your T3x barrel. Fire one shot, then clean the bore completely. Repeat this process for the first 5 rounds, then fire 3-shot groups with cleaning between groups for the next 15 rounds.
This process removes any residual manufacturing compounds and smooths microscopic tool marks in the bore. After approximately 20-30 rounds total, your barrel is fully broken in and will maintain peak accuracy with routine cleaning every 20-40 rounds depending on ammunition type.
Yes, the T3x trigger is user-adjustable from 2 to 4 pounds without requiring gunsmith tools. We ship rifles with the trigger set to 3 pounds from the factory. To adjust the pull weight, remove the stock and locate the adjustment screw on the trigger mechanism.
Turning the screw clockwise increases pull weight, while counterclockwise rotation decreases it. Make small adjustments and test the trigger after each change. We recommend keeping the pull weight above 2.5 pounds for hunting applications to maintain an appropriate safety margin.
We recommend medium-height rings for most standard rifle scopes mounted on the T3x integrated Picatinny rail. Medium rings provide adequate clearance for objective lenses up to 50mm while maintaining a comfortable cheek weld on the synthetic stock.
For compact scopes with objectives under 40mm, low rings may work depending on the specific scope’s dimensions. For larger tactical scopes or those with oversized turrets, high rings ensure clearance between the scope body and the receiver.
The T3x synthetic stock and metallic bolt shroud are designed specifically for reliable operation in extreme cold. The synthetic material won’t warp or swell with temperature changes, maintaining consistent zero in freezing conditions.
The bolt operates smoothly even when temperatures drop below zero Fahrenheit. We’ve designed the trigger mechanism to function reliably in cold weather without the sluggish performance some triggers exhibit when lubricants thicken. Many of our customers successfully hunt in temperatures well below freezing without reliability issues.
With 150-grain ammunition, the T3x .308 delivers ethical hunting performance on deer-sized game to approximately 400 yards with proper shot placement. Beyond that distance, bullet energy and velocity begin to drop below ideal thresholds for reliable expansion.
For target shooting and steel plate competitions, the rifle remains accurate well beyond 600 yards when using quality match ammunition. We’ve documented consistent hits on 12-inch steel targets at 800 yards during testing, though wind reading becomes critical at those distances.
Yes, the T3x action is compatible with a wide variety of aftermarket chassis systems and traditional stocks from manufacturers like KRG, MDT, and GRS. The action uses the same footprint as previous T3 models, ensuring broad compatibility with existing aftermarket products.
When upgrading to an aftermarket stock or chassis, verify that the product is specifically designed for the T3x pattern. Our modular synthetic stock system provides excellent performance for most applications, but competitive shooters often upgrade to fully adjustable chassis systems for maximum customization.
