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. (http://www.thehighroad.org/showthread.php?t=678753)

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:
In rifle cartridges, the 6-1/2 small rifle primer should not be used in the 17 Remington, 222 Remington, 204 Ruger or the 223 Remington. The 7-1/2 BR is the proper small rifle primer for these rounds.


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.

They work great in .38SPL loads.
But Remington also has SPP so what good?

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.
