| I bought 5000 Wolf small rifle primers when they first came out. I recently used up the last of my other primers and started to use the Wolf primers. I loaded a round of .223 with my normal load and test fired it. The primer was pierced by the firing pin. I loaded on a grain under and still experienced a pierced primer. I see people on the boards using Wolf primers all the time. Is there a difference in cup thickness between the SR and the magnum primers. I thought I read about a primer made specifically for the .223. Any insight would be appreciated. |

Yes, there is generally a cup thickness (ETA or harder material) difference between a normal primer and a magnum. The magnums are thicker (tougher) then a regular primer. Wolf makes a .223 Specific primer but I have no first hand knowledge of them. ETA to further add: Check your firing pin to make sure its not chipped or damaged. |

This came off of the Wideners web site. http://www.wideners.com/itemdetail.cfm?item_id=8975&dir=278|284|737 I have no first hand knowledge fo the wolf primers however as soon as I can get a local group buy or they show up in one of the local shops I'm going to gt some of the Wolf LRM primer to use in my X39 reloads.
SMALL RIFLE PRIMER (part # QQQSR) - Used as a standard small rifle primer. Perfect for the 30 carbine and 223 standard loads. Many people use this primer in bench and other loads for the 223. This primer is a copper colored primer. SMALL RIFLE MAGNUM PRIMER (part# QQQSRM) - This is the primer we had before for use in the 5.56 loads and hot 223 loads. A thick cup for the higher pressure. We sold a lot of these primers earlier this year. The new lot is brass colored instead of nickel. SMALL RIFLE 223 (part # QQQSR223) NEW NEW This is the newest primer available in the Wolf line. It is ever so slightly hotter than the small rifle magnum primer and it comes with a brass colored thick cup. This primer can be used in place of the SRM primer or used when a different powder is used that is hard to ignite. |

You might want to check your rifle's headspacing. Pierced primers can be caused by excessive headspace in some instances. If headspace is good, I'd measure some sized cases to make sure your resizing die is within spec.
Also, what load data are you using? I've found the data for 223 published in Speer #14 is dangerously hot. |

Thanks for the quick replys guys. I am an experienced reloader and the problem definitely lies with the primer not the guns. I have had this same problem with a Savage bolt gun and 2 AR's.
From the description in the above replies it appears these primers are for lower pressure loads and will not take full pressure .223 without problems. They are the copper colored primers and are not magnums. I have never had to use magnum primers before although I know they are recomended for ball powders. Looks like I need to just go back to my standard WSR or CCI 400's. I guess I will load up some .38 specials or 9mm with these provided they are sensitive enough to ignite. I don't know why Wolf would sell primers branded as small rifle primers if you couldn't load all small rifle cases with them.

I don't know why Wolf would sell primers branded as small rifle primers if you couldn't load all small rifle cases with them. The primers you have are meant for 30 Carbine, 22 Hornet, and other low pressure rifle rounds that use the small rifle size. In Wolf brand you want Wolf "223", or Wolf SRM primers for 223 loads. Both work great in 223 loads shot in an AR. More info about Wolf primers in the "Useful Threads" thread near the top of the page. |

This is the primer I am currently using in my 6.8, so far I've had no problems and my accuracy actually improved slightly over the CCI & Win I had been using. I see no reason why it wouldn't work in 5.56/.223. |
| The Wolf primers I purchased are marked "for 5.56mm loads". They are magnum only in the sense that they have a magnum thickness cup to withstand higher pressures. The original labeling was misleading or confusing depending on your perspective. Part of it was lost in translation. I personally think that Wolf's adding a real magnum to it's lineup adds to the confusion, I'm just glad I got my 5.56mm primers when I did. |

If you are anywhere close to Hubert/Swansboro, Flatwoods carries Wolf primers. Although I don't recall what sizes they had sitting in the shelf. |
