I'm in the process of setting up for reloading 223/556 for an AR15. I've read that I should be loading CCI 41's as this is the NATO spec. Is this really necessary? I've done some light research and read that the CCI 400 (Small rifle) primer housing is .020" thick, the CCI 450 (Small Rifle Mag) is .025" thick. My reading also has recommended the CCI 450 if the CCI 41 is not used.
So, what do you guys and gals load in the primer department? Any slam fires from that free floating firing pin using anything but CCI 41s? |

There is nothing wrong with using 41's but by the time this thread runs it's course I think most people will say, including me, that regular small rifle primers have worked fine for them. Including small rifle magnum primers and small rifle bench rest primers.
The one you want to avoid for .223/5.56 caliber is the Remington 6 1/2. They are mainly for lower pressure calibers such as 22 Hornet. Motor |

I like 400s for plinking loads, 7 1/2 for target and precision, and the Tula 556 mag primers for full boogie.
|

I use the 400's for lighter loads. 450's for hotter loads as I've seen some flattening with the 400's in my "hotter loads".

CCI 400 for 223 and 9mm (pistol) has worked for me You use a rifle primer in a pistol cartridge? View Quote If I remember correctly, the CCI 400 (SR) and the 550 (SP Magnum) are the same primer, and can be used interchangeably. DO NOT TAKE MY WORD FOR IT, RESEARCH IT BEFORE YOU TRY IT!! That being said, I use CCI 400 for my 55gr plinking loads, and Rem 7 1/2 for my defensive loadings. Both have served me well, and I've used several thousand of each over the years. |

I finally used all the Wolf's up, now on to Tula's, I'll be darned if they dont work too.

I use CCI 400s. I'm still in the learning faze but they work for some of my test loads.

My progressive press (Lee Load Master POS) calls for a primer explosion shield if using other than CCI or Remington primers.
I thought, when I purchased it, the information included stated CCI or Winchester. Either way, I've used both Winchester and CCI primers with good results. |

I have used CCI #41 because I got 2K for last Christmas and have just about used them up. I also have a stash of CCI 400's that I will be switching to shortly.

I use CCI 450 for ball powder and Rem 7.5 for stick powder.
Rem 7.5 works for ball powder but some recommend a magnum primer with ball powder since it is harder to ignite. |

View Quote I'm pretty sure remington 7 1/2 primers are magnums I usually use wolf and tula magnum primers but have used cci 41's in the past |

Tula small rifle magnum and CCI450s with H335 for me. Over 4k+ rounds total with those primers, 0 slam fires, 1 failure to fire because of powder contamination. You do not NEED 41s at all

As you can tell, ABQ87120… everyone has their preference in the primer-department. Once you begin into reloading, you will also find what works best for you and your firearms. That's all part of the fun.
What you'll learn in time is that some of the powders used in certain applications may call for a magnum primer. (Reloading books and online reference will aid in this.) While in other circumstances, any appropriate primer will get the job done. And in the best of circumstances, you can find primers at such a good deal – you will purchase them for use at a later time in something you may not be loading for, yet. So, if it would make you feel more comfortable to use the CCI #41s and you can justify the costs, then by all means go for it. All I'm saying is that once you begin reloading, there may come a time when that particular primer or component that you've tested and become dependent on may not be available. Try not to limit yourself. Take a day or an evening to work up a particular load for your rifle using a specific set of components. Then, dedicate another day or evening to using something else. The more you experiment with different primers and powders, (even using the same brass and bullets), the more versatility in your reloading. And most of all, have fun doing it. |

I just realized from this post that anytime we can sit around debating which brand of primers to use, well, we're living in the "good ole days."
Wasn't that long ago people were loading whatever they could get their hands on. Might not be too long before it's that way again so while you can, remember, buy'em cheap and stack'em deep! ETA: Fixed grammar error. |

As was said, many of us get a combo we like and stick with it. For me and .223/5.56, I use H335 and Win SR primers for all my general ammo (10s of thousands of rds so far) but use TAC and Remington 7½ primers for my long range 68+grn loads (thousands of rds so far). For me and my equipment they work best. However, YMMV.

I finally used all the Wolf's up, now on to Tula's, I'll be darned if they dont work too. View Quote A lot of the precision crowd have left the CCI and Rem 7 1/2 primers for the Wolf / Tulas. The argument is that one should use the wimpiest primer that will light the powder. Two reasons 1) Smaller primer flames tend to be more consistent. The Rem 7 1/2 has by far the largest flame. 2) The "oomph" from a primer contributes more to peak pressure than equivalent "oomph" from powder ... the theory goes, you should use a lighter primer and more powder to get your velocity. You see a lot of highpower shooters using the Wolf/Tulas. The small rifle primer .308 brass seems to be popular with the Palma guys. At distance, ES in velocity significantly affects vertical spread on target. I use Rem 7 1/2 for my .223 loads, including 600 yard cartridges for highpower. And I'm 1000% sure it isn't my primer choice that's stopping me from cleaning that target. That said, when the ~19,000 Rem 7 1/2s I've got left are gone, I'll probably give the Tulas a serious go. |

Ditto. I load hot but not screaming hot load (24.0 gr Varget/80 gr SMK) with WSR primers - no problem. In NM parlance, you might say this is habanero hot but not ghost pepper hot. View Quote View All Quotes View All Quotes Quoted:

I have and use plain Winchester Small Rifle primers... some say they can cause issues. So far as I can tell, I haven't had any. I would have gone with something known to be less likely to be pierced or whatever but nothing else was in stock when I got a brick in Tulsa.

Between Winchester, CCI, Rem 7.5 and Wolf, Wolf is more consistent (lower SD) Have not tried Tula, but they are supposed to be that same as Wolf.

I use Wolf Small Rifle Magnums or the .223 primers. I have 15,000 primers unopened and just opened a 5000 primer box.
This reminds me time to order more primers. |

gasdoc09. I'm pretty sure Tula primers ars currently on the banned import list. So switching to them may not be an option.

I bought a couple sleeves during the Great Primer Shortage. When I get around to trying them out, it'll be a great tragedy if I like them and can't get any more. |

CCI 400's for usual stuff
Fed 205M for precision work (sssshhhhh. dont tell anybody. These are the supposed slam fire voodoo ones......) |

I have Remington, CCI (standard & #41s), Winchester, and Wolf primers...and have yet to find a reason to use anything but the Wolf. At one point you could get them for around $15/k, and they have shot just as well as anything else I have tried. Of course, I haven't needed to buy primers in a while, so I have no idea what they currently cost. I will say this, though, they have been just as accurate as other small rifle primers in my AR's, with very consistent velocities.

My standard primer for .223 is the CCI 400. That's for everyday shooting.
When shooting for extreme accuracy, I use Federal Gold Medal Match primers - 205 Small Rifle Edit: Never had a slam fire. I don't shoot 9mm. |

I've gone to the Tulas after using WSR and plan on getting a lot more for my .223.
