Hi Guys!
Hope some of you will be able to help me out on my reloading for 5.56/.223rem. (I shoot them in my Daniel Defense M4v7s with 11.5inch barrel)
So here is the story. I'm starting to reload this caliber (already reloaded 5k round of 9mm). The issue I have is that once I shot my brass (good firing feeling, extraction and cycle) the cases I get are really dirty (see pictures).
I started with these components:
-Magtech small rifle primers
-Vitha N133 powder
-Frontier 55gr bullets (no crimping grooves on them)
Started from the lowest load data to the highest.
The cases got really really dirty in this case. I did crimped them quite a bit and had some good neck tension, and with any load it got very dirty.
So I thought that it might be a problem of too slow powder for my barrel lenght so I tried the Vitha N130 powder which is supposed to be a faster powder.
Ended up with the same issues.
Then took an even faster powder the Vectan SP10 (French brand for those who know) which is faster than N130 but slower than N120 for those who are used to Vitha powders.
It got a bit better but still no so well.
Then tried with other primers because with the magtech I felt that sometimes, when firing I noticed some delay (few milliseconds but still noticeable) between the firing pin cruching the primer and the effective shot, somthing like slow burning primers. So I tried with Geco small rifle ones, and it got again better but still not perfect (the pictures are with geco primers and SP10 powder so the best results I could get up to date.
So here is my question: what cause this? What can I do to solve this issue, knowing that when I shoot some manufactured brass (GGG, Geco, S&B) thay all get out really really clean.
Thanks in advance for your help guys.
