So I hit the range this morning, talked to the "Range Safety Officer"
and he didn't let me use my camera while I was there, something about employee safety. So video but I can tell you it shoots and shoots well. I was getting 3-4 inch grouping at 50yds off hand although it certainly has more potential accuracy, I just wasn't doing my part I'm sure. That and the receiver cover mounted scope was not what I'd call sturdy, i could rattle it back and forth with my hand but I had no other sighting option.
Anywho, it ejects like it can't stand have ammo in it; it was launching the cases into the air and hit the roof of the metal cover hard enough to make it *ping* each time. I decided to recover some cases from each string of firing just to keep for a souvenir of its first firing and to just inspect for my own curiosity. I did notice some concerning features each spent case shared and I took some pics so maybe someone would recognize any of these.
This shows the case necks and how they are damaged rather consistently with a flattening of one side of the neck. I thought this might be from being thrown into the air with violent force but each ejected case had similar damage.
This here shows an odd score mark along the case body about a quarter of the way up. It's around the same spot and size on each case and I'm not sure what is causing it, perhaps a burr in the chamber?
Above shows marks along the shoulders of the cases that all bear resemblance to one another, note how each shoulder scuff is almost in line with the mark on the case body and is consistent on each casing. Also, if you look to the far left case's neck you can see the severity of the indentation and on the far right casing there is almost a textured buildup along its indent.
Above is a general shot of the primer strikes; all seem well placed and perfectly struck. I was shooting a mix of TulAmmo 124gr FMJs and Wolf 124gr HPs that day. If you look closely you can see some indentations and damage to the base and rims of each case.
Lastly is a picture of the three most severely damaged case bases and rims. It isn't alot of damage nor is it incredibly noticeable, I just happen to be a little more nit picky when it comes to details like this. I suppose my question is this: Do I need to worry about any of the above phenomena? And if so, what can I do to correct it? There were no failures in the carbine's function that day and we put around 100 rounds through it just to test it out and get a feel for it. Any information is greatly appreciated.
