I just loaded 200 rounds of 300 Whisper.I accidentally put CCI 550 Primers instead of CCI 450.These are not hot loads will they be alright are should i pull them ? They are both mag primers but one is pistol and the other is rifle. Also this is out of an AR not a contender.Didnt know if it made a difference.

I'm not 100% certain,but, I think rifle primers have a thicker cup than pistol primers. If you're saying you used pistol instead of rifle, and they're not hot loads, you shouldn't have any trouble, but I'd check with CCI/Speer just so I could sleep peacefully. jd45.

If they are not hot loads you should have no trouble. They may not fire to the same point on impact, but they should be close.

The rifle primers do have a thicker cup to handle higher pressures and stronger primer hits. You will probably lose some vel and the extreme spreads will more than likely be greater. The worst thing that could happen is that you'll get pierced primers. I would just shoot them and if you start getting holes in the primers then pull them but other wise just shoot-em-up.

I would e-mail SSK and ask them about it. They will know.

What do you mean by "not hot loads"? How far off of maximum are you and with what powder and bullet?

Why don't you just pull them and not worry about it? The only thing you will lose is the primer if you use a kinetic bullet puller.

That's not exactly a safe alternative. Not the bullet pulling, but the de-capping of live primers. The will occasionally go off.

Sorry its been so long for reply been away.The load was 14.2g ww296 under 165g rem bulk psp.I use this for a plinking load.I took these to the range with me and shot 10 rounds no problems with the ammo.The problem was with me i just didnt feel right shooting them knowing they were the wrong primers.I put them in my too pull later drawer.

Thanks for the reply's i know i can get good answers here for any problems.One thing i have learned in many years of reloading.I always double check everything before i write my labels on my reload boxes.If i had wrote out my labels first i would have never found what i had done.THANKS AGAIN.

Reed;

Yes! You are absolutely right. I should have followed thru and clarified that once the bullets were pulled and the powder dumped, to take them to the range and fire the primers off.

I've heard that said before but have never known anyone who has actually had it happen. For various reasons over my 35-40 year reloading career I've done it several hundred times at least and maybe over a thousand and have yet to have one pop. While I'm not saying it is impossible to make one pop while decapping I think it is darn near so.

But for safety sake one can spray WD-40 in them and kill them 100%. Me I just decap.

Before doing that much effort tho I'd contact both SSK and CCI and ask. Small pistol primers are designed for pressures to about 35,000 psi and likely have a fair margin over that before anything extreme happens. I have no clue to what pressures you've loaded them but SSK or CCI or perhaps your powder maker can help answer that question.

GB,

I have had it happen several times. No damage was done, other than a load of laundry for my pants. It's never a good idea to do it, though it is rare for it to happen.
