I guess I can use them in a 9mm but not a .223...I made a mistake...
- Cases that utilize small rifle primers and operate at moderate pressures(40,000 psi) should use CCI 400, Federal 200, Rem 6 1/2, or Win SR. Such cases include 22 CCM, 22 Hornet and the 218 Bee. These primers are also used in heavy handguns such as the 9mm., 357, etc. Other cases that use the small rifle primer can use the above primers only if moderate loads are used. Keep to the lower end of reloading recommendations.
- Cases that utilize Small Rifle primers and operate at higher pressures (55,000 psi) should use CCI 450, CCI BR4, Fed 205 and Rem 7 1/2.
- With large rifle primers all being the same thickness, choose a primer that makes the most accurate group, is the shiniest, cheapest or whatever, as they all have

I'm not necessarily challenging your statement, but where did you come up with that info? I've never heard of 6 1/2s being any issue when used in .223 or similar cases.

It's on Rem web site and I believe it may be (small print) on the box of 6 1/2 primers. From Remington's Web Site. In rifle cartridges, the 6-1/2 small rifle primer should not be used in the 17 Remington, 222 Remington or the 223 Remington. The 7-1/2 BR is the proper small rifle primer for these rounds. .

Jimmy, Yep, I learned that the hard way..  I loaded up some 222 ammo doing the test load thing, and one group I loaded used Rem 6 1/2's. First round down the tube with a 6 1/2 primer pierced the cup, allowing a bunch of gas to flow freely over my head, and face.  I won't be doing that again.

Look on the bright side, it's a good excuse to buy a Hornet or Bee.

Good point, but I went back to the gunstore where I have shopped for 20 years and the guy let me exchange them for 1000 CCI 450 small rifle primers.
I guess these will work in a .223 Remington!

The 450 is an excellent primer for the 223.

I thought that too but in just about every instance the 450 has outshot the 400 in my 223, no matter the powder.

Right now I am going to back off a grain, stick the 450 under the shell, load a 62 grain TSX and try it out!

I use CCI 400s and CCI BR-4s. And 71/2s.

If you want to use them in the 223...
loads with 12 to 16 grains of SR 4759 with 55 grains and under, they will work just fine...
loads of 4198 with say 19 grains and under will also give low enough pressure to use them...
under 17 grains of 4227 also...
and of course those accursed blue dot loads with bullet weight below 55 grains and using 12 grains of powder or less...
with primer shortages, and small pistol is all one can find available, these light loads have allowed me to be shooting these kind of primers...

Well, I learn something new every day! Thanks for the info guys, I've only ever used 7 1/2BR in SR primers, and the only cartridges they've gone into for me are .454 Casull, .357 Max, and 6PPC. Obviously haven't had any problems, but I've never tried switching out to 6 1/2s either, and now I never will! Thanks!
