Re: New Brass, .243 Cracked neck
Well I'm bringing up this post again because I am 99% sure it was my error rather than bad product. I just got back to reloading in the last couple weeks and re-inspected the cases as well as sizing and trimming some new ones.
In the process I have noticed a few cases that are slightly folded so I think I over lubed them. The cracks then are caused from burn through. And maybe a combination of a light load causing some high pressure.
I came to this conclusion by resizing some more of the Winchester brass with my normal amount of lube on it. I had a few fold slightly on me. I then tried without letting it dry and had a more significant fold. Finally I did a few more with significantly less lube on them and they came out fine.
I know back when I rolled my cases in lube I did a few dry to clear up the due a little bit because of the residual lube it picked up. I wonder if maybe the spray lubes leave some excess in the due as well.
I guess the moral of the story is less is better and pay more attention on my QC. I was in somewhat of a hurry with these and let the inspections slip a little bit. I should have just bought some factory rounds for her to shoot so I had time to do things right the first time. I guess when you start to get over confident and rush $£|- happens.
