Lads I bought a bunch of primers cheap thinking they were sm rifle, then I find out it is not advisable to use them in 223 size cases. Is it alright if I use these for 221 Fireball and Hornet size cases?

Thanks Greg

The intended designation.

Don't happen to know the 221 Fireball specs on pressure, so I can't cmt on using the 6 1/2's for it. But, they are suitable for the Hornet.
Last summer, I did load some 6 1/2's up in a 223. The first shot pierced the primer, so I stopped there, and unloaded the others when I got home.

SAAMI pressures for both cartridges is 52K CUP, I`d forget the 221 FB and stay with the Hornet useing these primers.

Those Rem 6 1/2 primers are THE primer for my hornet. It's the only primer I'll use in it, and I get amazing accuracy from mine with Lil Gun and Hornady 40 gr vmax's.

Thanks Slim

that is how I'll use them

I use 6 1/2 primers all the time in 223..

but the important thing is to remember they are intended for cartridges which are shot at lower pressures..

however shooting a 223, for example and you know your pressure is only in the 40,000 PSI range or so, no problems are presented.

just match your load to the pressures the primers were intended for.. not necessarily the case they say to use it in...
