Positioning and Brand Heritage
The RWS 5341 occupies the top tier of the RWS large rifle primer family, sitting alongside its magnum counterpart, the RWS 5333. RWS has been a leader in explosive technology since the 19th century, and the RWS 5341 represents the culmination of over 100 years of refinement in priming chemistry. While many American primers focus on high-output brisance, the RWS 5341 is designed for “controlled” ignition, ensuring that the pressure curve initiates identically every time the firing pin strikes.
The SINOXID compound used in the RWS 5341 was a revolutionary advancement in ammunition safety, providing a non-corrosive alternative that does not produce the barrel-damaging salts found in older formulations. This commitment to quality has made the RWS 5341 the primer of choice for European hunters and Olympic-level target shooters who demand that their ignition source be as precise as their optics.
Compatibility and Safety Constraints
The RWS 5341 features a nickel-plated brass cup that is engineered to metric tolerances, which are occasionally tighter than those found in domestic American components. When seating the RWS 5341, it is vital to ensure it is positioned 0.003-0.005 inches below the base of the case head. This allows the internal anvil to be properly “set,” ensuring the primer is sensitive enough to ignite upon the first strike but stable enough to resist accidental discharge.
While the RWS 5341 is durable, it is a standard rifle primer, not a reinforced military primer. Users of semi-automatic rifles like the M1A or AR-10 should ensure their firearms are in good working order and that primers are seated deeply to avoid the risk of slam-fires associated with floating firing pins.
Any primer substitution requires a 10% reduction in powder charge. Because the RWS 5341 has a unique brisance profile, it may produce different pressure characteristics than domestic primers. Always drop your starting load by 10% and carefully monitor for signs of overpressure as you work the load back up.
Recommended Cartridges and Applications
| Cartridge | Primary Application |
| 308 Winchester | The gold standard for short-action precision and target loads. |
| 30-06 Springfield | Enhancing the accuracy of classic long-action hunting rounds. |
| 6.5 Creedmoor | Large primer pocket variants used for extreme long-range. |
| 243 Winchester | Uniform ignition for high-velocity varmint and deer loads. |
| 270 Winchester | Consistent velocity for standard-bore mountain hunting rifles. |
| 7mm-08 Remington | Maximizing the precision of medium-bore hunting platforms. |
| 6.5×55 Swedish Mauser | A natural heritage match for traditional European calibers. |
| 8×57 Mauser | Reliable ignition for both vintage military and modern sporting rifles. |
The RWS 5341 is an exceptional match for the 308 Winchester. Its consistency allows shooters to find the “node” in their barrel’s harmonics with fewer rounds, as the primer itself introduces very little variable into the equation.
Powder Pairings
The RWS 5341 performs best with high-quality Extruded (stick) powders that are naturally easier to ignite than heavily deterred ball powders.
In the 308 Winchester, the RWS 5341 is a legendary pairing with Vihtavuori N140 or Hodgdon Varget. For those loading the 30-06 Springfield, using the RWS 5341 with IMR 4064 or Accurate 2495 provides a very stable platform for match or hunting use.
While it is a standard primer, the RWS 5341 has sufficient energy to ignite moderate charges of Spherical powders like Winchester 748 or Hodgdon CFE 223, provided the case is not of magnum capacity and the temperatures are not excessively cold.
Comparison and Alternatives
The RWS 5341 is often compared to other premium large rifle primers used in competitive and high-end hunting circles.
- Federal GM210M: Its primary match-grade rival; the Federal is typically softer and more sensitive than the RWS 5341.
- CCI BR-2: The American benchrest standard; very consistent, but lacks the nickel-plated finish of the RWS 5341.
- Remington 9-1/2: A much hotter standard primer that is less focused on pure match-grade uniformity than the RWS 5341.
- CCI 200: A reliable, general-purpose primer that is generally considered a step down in consistency from the RWS 5341.
- Winchester WLR: Known for a very hot spark; good for hunting but often lacks the precision reputation of the RWS 5341.
- Federal 210: A standard sensitivity primer often used in high-volume reloading.
- Sellier & Bellot V360587: Another European alternative that offers reliable performance at a typically lower price point.
- Fiocchi Large Rifle: A dependable European primer that provides consistent ignition for standard rifle loads.
FAQ
Is the RWS 5341 a magnum primer? No, it is a standard large rifle primer. For magnum applications, RWS offers the RWS 5333.
Why are these primers silver? The RWS 5341 uses a nickel-plated brass cup, which provides a smooth seating feel and prevents corrosion over long-term storage.
Can I use the RWS 5341 in my 308 Winchester target rifle? Yes, it is considered one of the best primers for the 308 Winchester, especially when chasing sub-MOA accuracy.
Are RWS primers corrosive? No, all modern RWS 5341 primers use the SINOXID non-corrosive priming mixture.
Will the RWS 5341 fit in all Large Rifle brass? Yes, it adheres to standard Large Rifle primer pocket dimensions, though its metric tolerances mean it may feel slightly tighter in some domestic brass.
How do these perform in cold weather? The SINOXID compound is highly stable and designed to perform reliably in temperatures ranging from extremely cold to very hot.
Conclusion & Expert Verdict
The RWS 5341 is an investment in precision. For the reloader who has already optimized their brass, projectiles, and powder, switching to the RWS 5341 is often the final step in eliminating variables from the ignition process. Its German engineering and heritage of match-grade performance make it a standout choice for anyone serious about accuracy.
Expert Pro Tip: Because of the nickel plating on the RWS 5341, they can be slicker during the seating process. Use a high-quality hand-priming tool to “feel” the primer bottom out in the pocket. This tactile feedback is essential for ensuring the 0.003-0.005 inch seating depth required for perfect ignition consistency.
