Personally i have no issues with case dents in 223/5.56 as fire forming these cases is very common (300 blackout comes to mind). As long as there are no cracks, the dent isn’t deeply pierced (like a pinhole with a hard stop as if you’d used a punch), it’s not in the top of the neck where sealing or trajectory will be affected, or the dent doesn’t mis-shape the round so i have to use the pusher to get it to chamber..... it’s going down range.

below are some rounds I’d like to hear opinions on. These are mixed 223/5.56 rounds.

First picture i would use. second picture i would not and the two on the left in the 3rd picture i would probably use. Many times anything right next to or on the shoulder will cause the round to not chamber. I would probably also drop them in a case gauge before loading just to make sure they would fit in a chamber. A dent(especially with a crease) going in sometimes causes a portion on the outside of the dent to raise up. The two on the left that i said i would probably use would certainly be dropped in a case gauge.

I had a box of them, I got the sender to take them back. I forget who it was and I can't find the pics, but they were just like thank.

Backstory on my 4 day project..... I’ve bought seconds before earlier in the year when the coof first started and made everything disappear. I have no issues with seconds because there is no problem with fire forming rounds that are still safe so if I can get them I’ll take them. However a few days ago I was offered something entirely different. I was offered 3000 of them and I have been knee-deep in going through multiple ammo cans for days now.

with the current pricing being about a dollar per round, 18¢ is right up my alley. There will be some ill have to re-case, but i have powder, projectiles, and primer for less than i could ever buy them. Its a no brainer.

most are decent, a few have the issue below. The dings on the neck and shoulder are probably going to keep them from seating and sealing properly. If anyone has a different opinion, I’m listening. Same pic with and without flash because ......shadows.

Did they come like that? Or are they reloads you did? I had the dents like that when i started to load rifle. To much lube was the culprit.

I would get a case .223 case gauge and test them to see if they fit. Nothing worse than getting a round jammed in a AR and trying to extract it. Many of those with the dents on shoulder i suspect will not chamber. Not sure what caliber the others are but if it's a bolt gun it;s much easier seeing if they fit or not without jamming them in the chamber so they stick.

I only have a hand full with dents this bad and he fireformed these with ease.

I'm not saying the dents won't blow out and fireform, I'm just saying depending on where the dent is and how severe that i may not chamber. If the round the guy had in the video wouldn't chamber he could simply pull it back out. In a AR platform with the bolt jamming it into the chamber they don't usually come out so easy which is why i suggested checking them with a case gauge. Also pay attention to the last thing he said, many times dents will rupture especially if the dent has a crease.

You can fire form dents out fairly easily, and I have done so, but a bolt or single shot rifle is best for the task, as Square target said.

Heres the before and after on a few i shot today. The two i do not shoot are heavily creased (avoid ruptures) or have a ring near the bottom (Avoid separation).

Since these were done on a dillion 1050 super the defects are all the same so i have 100-200 of each kind of defect. Sometimes it’ll be too much oil, sometimes the machine will be out of adjustment. Either way it makes a few hundred of each so if i shoot a couple and see how they form I’ll know how the rest go.

you can see how these formed. Before and after.

Here is the shot of the above case and my (new) Caldwell chrono. Then below is that case inside to see how the internal wall looks.
