    Guys, I finally went to the dark (actually, black) side and got a Colt 6920LE. With components being hard to find, I bought a box of Remington 6 1/2 primers from a fellow Bullseye shooter. But Remington, on their website, says they are not suitable for use in a .223. I have seen conflicting opinions about flame cutting bolts, blown out primers, and on the other side of the coin, they are fine if pressures are kept below 55000 CUP, "I've used them for years", yada yada yada.

    So, can I use them in my sweet new M-4 or not? If not, can I use them in pistol rounds? Yikes, I don't want to hurt my Colt!

    I would not, the walls are really thin and you can damage yor Bcg or firing pin. This is just a example of what piercing the primer could do.

    Just use caution on using them. They are a thinner cup.

    Remington specifically warns against using them in .223...maybe they are on to something...

    So a 6 1/2 is listed as the only small rifle primer they make. But it is not suitable for use in ANY .223? I am confused especially considering that is probably one of the most commonly reloaded round that uses that primer.

    Well, they put the warning on their site, and upon closer examination, on the box of primers. But I believe their 7 1/2 will work.

    That's not from pierced primers, that's from excessive leakage around the primer cup itself. Loose Primer pocket, excessive pressure, etc.

    If the primer was pierced there would be damage around the firing pin hole. From the looks of the ejector, there might have been lots of extra pressure.

    I know the OP has the 6-1/2's and would like to use them but if it were me, I'd look for a trade into some more suitable primers. CCI SRP's are better. Have personally had great luck with the Wolf/Tula .223 Primers. Good luck on finding any of any kind right now.

    I was able to trade 3k small pistol primers for winchester and CCI small rifle primers. Will try to sell the Remington 6 1/2s, but will offer a disclaimer in the ad. Wish the seller had done so for me. Also, I should have read the danced box!
