| My friend just gave me 1000 remington 6 1/2 small rifle primers, can i use these for .223? |

I believe you can use those primers with the following limitations.
Light bullets only! 52/53 grain match bullets or lighter. Mid range powder charges should be considered maximum, these primers are designed around 40,000 psi if I remember correctly. As long as use use lower velocity loading you should be OK. They will not hold pressure like a standard small rifle primer does. Always remember that. |

You'll be able to use the 6 1/2's in .223 Remington if the pressures are kept low, around 38k to 40k psi maximum. Find load data that includes the pressure. Minimum start loads will run about this level.
As for pistol cartridges, yesterday I tried some with IMR 4227 and H110 in .22 Jet cartridges because I had poor consumption of the powder with small magnum pistol primers on my first outing. I'm switching to the 6 1/2's for this application, and I'm going to experiment with them in other large pistol cases. |

Thank you everyone for the replies. |

Thank you everyone for the replies. Don't get over confident. Hold to the mid pressure loads. The primers you have are intended for cartridges such as .22 Hornet, not 50000 psi class cartridges such as the .223 Rem. You won't blow up, but you'll get tired of replacing firing pins and it's possible to ruin a bolt face with pierced primers. |

Very glad to see this thread. I just bought a 100 pack of 6.5's today. The only other srp's cabela's had were 7.5 bench rest. Are they safe for average .223 loads? Where the 7.5's magtech? I was thinking of getting them today too, but since my friend already gave the some 6.5's i decided to hold off. |

They might be labeled "benchrest", but they're a good heavy duty primer that work great in AR's. Magtechs are PR-SR. |

I got mine at graf and sons but they're out right now. Haven't tried them but powder valley is showing 223 wolf primers in stock right now for $25.50 per K. |
