    I've seen where everyone says not to use them in 223 because of the pressure difference of the 22 hornet that its intended for . But what about 300 aac blackout?

    Using SAAMI maximum pressures:

    .223 is 55,000 psi
    .300 AAC Blackout is 55,000 psi

    Give this old thread a read.

    That said we have no shortage of members here who have loaded the higher pressure .223 using Remington 6 1/2 primers successfully. Watching for pierced primers and burning on the bolt face.

    As we know Remington states:
    Since the .223 and 300 AAC Blackout share the same maximum pressure (from what I read and I may be wrong) personally I would look for a better primer for the 300 Blackout. However, that is your call. I am not saying the 6 1/2 primers won't work or your gun will explode in a million pieces and kill you, I am saying that I will not encourage you doing it.

    I'm not sure why Remington is still producing their 6 1/2 SRP since for the most part they are only good for the 22 Hornet especially since no harm would be done in the 22 Hornet with their 7 1/2 primers.

    They work great in .38SPL loads.

    The usefulness for this application surfaces when SPP are hard to find or when you buy some 6-1/2s then realize they are not appropriate for .223 Rem.

    I see lots of people saying they can be used in some pistol loads. Whoa about s&w 40

    I wouldn't use them in a high pressure cartridge. I limit them to .38SPL.
