Magnum Primer and How to Buy it

Magnum primers are designed for cartridges that have a powder load higher than 60 grains. They provide 74 fps higher velocity and have a longer flame than standard primers. In addition, they are safer to manufacture. Learn more about the benefits of magnum primers for your cartridges.

If you’re considering buying magnum primers for your rifle, you’ll want to consider how much powder you plan to load. These large rifle primers are designed to work with loads up to 60 grains, but anything above that can ruin them. They also have a different burn rate, which can lead to inconsistent movement.

In general, magnum primers are better for cartridges with longer powder columns compared to those with short, compact columns. This is due less to the amount of powder, but to the shape of the column. Also, magnum primers produce more gas, which can affect the speed of the bullet’s exit.

The extended flame length of magnum primers enables them to ignite powders that contain hard coatings at a higher temperature than standard primers. However, this does not mean that they will give a higher pressure. In fact, some magnum primers can even result in a lower pressure or velocity. Ultimately, your actual performance will depend on a combination of components and your reloading practice.

Magnum primers are designed for larger powder charges in large rifle cartridges. They are not intended to replace standard large rifle primers. Specifically, they are designed to ignite massive powder charges in Weatherby magnum cartridges. They should not be used interchangeably with standard large rifle primers, because they have different ignition characteristics.

The term magnum refers to a primer designed specifically for magnum ammunition. Large rifle magnum primers are designed to ignite cylindrical powders in cases of up to.30-06 caliber and smaller rifle magnum primers are designed to ignite spherical powders of at least 30 grains. Magnum primers are also recommended for use in magnum cartridges with “magnum” at the end of their names.

The difference in muzzle velocity between magnum primers and standard primers is small, but significant. While both primers have a similar velocity, magnum primers produce 74 fps more velocity than standard primers. The difference is significant enough to affect rifle powder performance.

Magnum primers have lower pressure and velocity. This is due to the balance of the fuel and sensitizing compounds. However, magnum primers should not be used in low-load applications. In fact, they can reduce starting loads by five to ten percent. This can improve accuracy. But be sure to check your load before you switch to magnum primers. Magnum primers are more expensive to produce, but they are also safer to use.

Magnum primers are manufactured in two ways: with a standard chemical mix, and with aggressive burn characteristics. The former was the preferred method by CCI until 1989, but the latter has a much more aggressive burn. After 1989, CCI switched to a blend optimized for spherical propellants, which produce up to a twenty-four percent increase in flame temperature and gas volume.
