My AR has to date functioned flawlessly with my reloads until this morning. After 10 rounds this morning of Winchester brass, a round from a new batch of BHA brass laoded ammunition failed to fire. No mark on the primer. I assumed out of battery due
to improperly sized brass. Some rounds would fire loaded from the magazine with the bolt locked back. None would fire when loaded from the magazine with the bolt sling shotted forwarded. Those which did not fire were hard to extract further confirming my belief I was dealing with improperly sized brass. To my suprise the loaded round I saved sized perfectly in the case gague as did the rest of the batch of sized but not loaded brass. Everything else seems in spec including case length. The only out of the usual aspect with this lot is a somewhat uneven neck trim with my Giraud trimmer which should not be a problem since the .223 head spaces on the shoulder. Guess I will use this batch in my bolt guns. Any ideas of what could have gone wrong here? Guess I haven't figured out how to double space a post. Advice here would also be appreciated. |

If you are crimping, you may have buckled the case shoulder and case will not fully chamber and won't fire. If you can post a pic of one of these it will help. Twist case half a turn before removing from Giraud, that evens out the trim. Double space after each complete sentance. Not in the middle of sentance. Like I did in this post. if you need help posting a pic, say so. It's not too hard, if I can do it so can you.

I use photobucket you can create an account there for free.
upload your pic to photobucket and then copy the image url, then when you create a post or reply to one click the little button that has the landscape picture of the mountains and sun, then paste the image url in to the popup window that will appear after you hit that button |

No crimp. Firing pin is working with other ammunition but I will remove and check.
Both sized case and the loaded rounds fit fine in a case gauge. Pretty sure the rifle is not going into battery with these particular reloads only. Unclear to me how rifle would be held out of battery if the round fits the case gauge. What else is different is the bullet. First time use of the Barnes 50 gr. Varmint Grenade. Loaded to 2.20 per Barnes. Guess I figured out the double space thing. Many thanks. |

Finally figured it out. I have three lots of brass in use. Two, both Winchester, were fred in an AR and full length resized. These work fine.
The lot that won't fire in my AR, BHA Match, I now realize were fired in a bolt gun and neck sized only. Lesson learned: Keep better records. What's interesting is the BHA neck sized only brass fits the cse gauge perfectly but will not allow my AR to go fully into battery. I would have to set back the shoulder slightly on the BHA brass to use in my AR, but will use the brass for the bolt gun it was intended for. Thank you for everyone's thoughts. |

Thank you for everyone's thoughts. drop in case gages for rifle only measure two things - headspace - OAL It's not a faux chamber like the pistol case gages are My fired brass fits perfectly in my Dillon .223 case gage |
