Cuz you use them in connection with BR reloading recipes and methods and components. For standard target and hunting loads dont even bother. Just buy standard, easy to find primers and get back on with life. |

Geland: When you tried those magnum primers, were they on the same day as you tried the standard primers? Weather has a lot to do with overall performance. |

My theory is that the fact that Magnum primer with its larger fire, saturated the whole (small) case of the 300Whisper, thus rises the pressure early in the ignition time and expend most of the energy in raising the pressure, and thus left little energy to propel the projectile downrange in the barrel. |

...Also they stated that since the front and rear of the powder are burning at once, going in different directions in the case colliding with each other, instead of a uniformed burn, its chaos inside the case. |

Sounds an awful lot like my guts after a big night on the turps. I remember back in the day when loading for pistol, there was an article in the AmericanHangunner called The 2.8gn Bullseye Surprise...story goes that igniting small charges of powder that lay along the bottom of the case could cause the powder to act like a cutting charge because the primer would "flash" across the top of the powder, igniting it all in one go causing it all to burn almost instantly. It was also believed that a magnum primer would exacerbate the problem. I regularly used loads of this size without problem, but I admit it certainly had me thinking. Cheers, Vince |
