Cartridge dimensions

The 5.56×45mm NATO has 1.85 ml (28.5 grains H2O) cartridge case capacity.

5.56×45mm NATO cross section

5.56x45mm NATO.jpg

5.56×45mm NATO maximum NATO cartridge dimensions. All sizes in millimeters (mm).

The rifling twist rate for this cartridge is 177.8 mm (1 in 7 in), 6 grooves right hand twist, Ø lands = 5.56 millimetres (0.219 in), Ø grooves = 5.69 millimetres (0.224 in).

According to STANAG 4172 and the official NATO proofing guidelines the 556 green tip 500 NATO case can handle up to 420.0 MPa (60,916 psi) piezo service pressure. In NATO regulated organizations every rifle cartridge combination has to be proofed at 537.5 MPa (77,958 psi) to certify for service issue.

STANAG 4172 defines the Belgian ball cartridge SS109 as the NATO reference cartridge and adds a considerable number of technical requirements like a minimum pressure of 88.0 MPa (12,763 psi) at the gas port 280 millimetres (11.0 in) down the 508 millimetres (20.0 in) long standard proof barrel and primer sensitivity that are not defined by civilian C.I.P. and SAAMI ammunition rulings and recommendations.

The NATO military alliance uses a NATO-specific recognized class of procedures to control the safety and quality of firearms ammunition called NATO EPVAT testing. The civilian organisations C.I.P. and SAAMI use less comprehensive test procedures than NATO.

The NATO Manual of Proof and Inspection AC/225 (LG/3-SG/1) D/8 stipulates each weapon and component considered vulnerable to the effects of a rapid change in pressure, for example barrels, breech blocks and bolts, will be tested by firing one dry round at a corrected minimum of 25% over pressure and one oiled round at a corrected minimum of 25% over pressure. Over pressure of 25% means 25% in excess of the service pressure resulting for the 5.56×45mm NATO up to 430.0 MPa (62,366 psi) (Pmax) piezo service pressure.

The service pressure is defined as the mean pressure generated by the service cartridge at a temperature of 21 °C (70 °F). Such a high pressure proof is conducted with both the weapon and ammunition conditioned to an ambient temperature of 21 °C (70 °F).

Each weapon will be individually tested, from an ammunition lot that produces a minimum corrected mean chamber pressure. The corrected proof pressure requirement (service pressure (Pmax) + 25%) for the 5.56×45mm NATO like the STANAG 4172 is 537.3 MPa (77,929 psi) (PE) piezo pressure. This pressure has to be recorded in a NATO-design EPVAT barrel with Kistler 6215 transducer, HPI GP6 Transducer or by equipment to C.I.P. requirements.

The US SAAMI lists maximum average pressure (MAP) for the .223 Remington cartridge as 55,000 psi (379.2 MPa) piezo pressure with deviation of up to 58,000 psi (399.9 MPa).

    As a competition Cowboy Action shooter for over 25 years, I have never had a primer related malfunction with this brand.

  2. Author Mark

    My standard for 45 acp. Wish this order would have made it to my door – ups lost it.

    Excellent product that goes “bang” every time. Very consistent results from load to load. One primer for magnum and standard large pistol rounds simplifies my inventory situation. Try them and you’ll love them also.

  4. vakfile

    I use them to load 45 ACP. Very happy with them.

  5. peter

    Remington primers are my favorite whether the smallest or the largest and all in between. I have never had one fail in four decades.

  6. dareln

    I ordered 5K of these LPPs when they were on sale hoping they would be good performers in my 45acp reloads. I am not disappointed! They are easy to seat (I thought too easy at first) and I am pleased with their performance. Every primer has fired so far… several hundred loaded and shot so far. I find these equal or better in quality to CCI LPPs. Great product

  7. vannick625

    I purchase these primers mostly because they were such a great deal. I have been pleased with performance. Ignition has been 100% so far (several hundred shot) and they are very easy to seat. At first I thought too easy, but I’ve had no problems at all in that regard. I find Remington LPPs to be equal to CCIs or Tula products. Look for your best deal and buy!

  8. swin89

    Unlike a competitor’s brand, I haven’e had a single misfire. They also feed perfectly through my old Dillon RL 450. Very pleased. Price was good also.

  9. joe

    Worked everytime I pulled the trigger. I use them in the .45 auto rim and .44 mag. No problums ever. Been using them for years……Doug

  10. luke89

    Excellent primer. Very consistent priming and to date I have never had a bad primer.. thats 40+ years and over 100,000 Remington primers.

  11. nathalie

    Use these primers for my 45 acp. Good functionality with no problems encountered. Don’t know of anything really negative to say about this product.

  12. swin89

    I started reloading at age 11. I’m 61 now and shoot 15000 reloads a year down from 30M or so when I was a Law Enforcement competitor. Now as then always Remington Primed. They’ve never let me down…..unless it was my fault. I’ve tried other brands but feel like I’m cheating on my wife when I do. Nothing is like Remington.

  13. licd

    My order for the #2 1/2 Remington primers was to add to my current supply. I’ve used the Rem #21/2 for 35 years of reloading and have never been disappointed.

  14. theo

    These are my choice for all the 45 ACP I load. I load a lot, shoot a lot, and these Remington primers NEVER let me down. The package/trays are very small and store more efficiently.

  15. mayday

    As a revolver shooter it was important to find a primer with a soft cup to replace Federal primers. The Winchester primers work fine which is important in speed competitions.

  16. samh

    finally in stock

  17. sorel

    Winchester primers have been around longer than I have and have always done the job exactly as expected. I will continue to use them.

  18. hinds

    I used them for reloading, as my Reloader hates CCI

  19. vin2

    I have been re-loading since 1978. Winchester primers are my go to primer when they are available. Very consistent in ignition and superior in performance overall.

  20. ppfa

    Work fine for me I like the non- plated finish.
