Advice needed

[B486]

I recently primed 100 virgin .223 cases using Remington 6 1/2 small rifle primers. After doing so I learned that these primers are not to be used for .223. I'm a little new to reloading so I don't know what to do here. Is it possible to deprime live primers? What else can I do? Thanks for any advice.

Not getting this? Primers come in six? basic configurations. Small and large rifle and large and small pistol, plus magnum primers, how many is that? If you used primers marked "rifle" and they didn't fall out, you did okay. BB

Remington does not recommend these (6 1/2) primers with .223. Yes you can deprime live primers. Just SLOWLY run em through your decapper or sizer die. Wear safety glasses. I have never had one go off, but I would still advise using safety glasses. You can reuse these primers in .22 Hornet or Small Pistol Magnum.

Remington does not recommend these (6 1/2) primers with .223. .

That is my understanding as well. They want you to use the 7 1/2 with .223/5.56

Thanks for the help.

It depends on the rifle they will be used in.

ARs have a floating firing pin, so when the bolt slams closed, the firing pin strikes the primer. If the primer cup is too soft the rifle can slam fire.

Remington recommends using the 7 1/2 primers for AR loadings. This is what is loaded into Remington ammunition made for the military.

CCI makes the #41, which is what they load in military ammunition. The #450, Small Rifle Magnum, primer is basically the same as the #41 (same thickness and hardness cup, same type and amount of priming compound), but the #41 has the anvil seated a few thousandths further from the cup. I use CCI #450 for my .223 rounds.

For other rifles, especially bolt action, the primer is not a big factor. ONLY semi autos with a floating firing pin.
