| I am fairly new to reloading and I have noticed that a lot of my Federal 223 brass is not to the minimum or max case length. I have been resizing them and then checking them in a Wilson case gauge and they have been fitting in the case gauge perfectly. Well today I went and tested some of the rounds that I have loaded and I am surprised that once that I checked the case length again after firing they are still below trim length. I was expecting them to be longer but they are not. I am missing something or is this normal on fired brass. If they are fired out of my rifle and they are shorter then trim length is that a sign that my Daniel Defense barrels are not head spaced correctly? |

Quoted:
Trim length gets longer after full length sizing. Trim length has nothing to do with head clearance or head space. Yes this. I see this mistake made way too often. Most of the time a case will get shorter when fired because when the body expands it draws the length in. |

I have since resized a few and they are with in specs now. Thanks everyone for clearing that up for me. Posted Via AR15.Com Mobile |
It was free and once fired so I'll keep it!
