Hey guys, I have a question on resizing. I have resized probably 1k cases at this point but i'm still not sure i'm doing it correctly. I am using a lee single stage press with a lee full length resizing die and dillon spray lube.
During resizing I noticed some of cases actually grew in length, I am assuming this is due to the fact that I don't lube the case necks. Is the expander catching on the case neck and pulling/stretching it out? If so what kind of lube can I use and how should it be applied?
Also how can I check for case head seperation on my brass with basic tools, as I notice a ring on some of the brass, but it seems like it is die machining marks scratching the brass around the web area.
As for adjusting the die per my rifles chamber... that didnt go too well. Most of the once fired brass I had would fit in the chamber without sizing, but not drop in with the "rattle fit" of factory ammo, however it would go in with a bolt assist tap to snap the extractor over the case rim. The factory cases would go in the same way with a tap on the bolt assist so a little more detail as to how I set up my sizing die would be appreciated as well. I have tried the touch the shellplate and then 1/4 turn more method and I was getting backed out primers. Leads me to believe I'm pushing the shoulder back too far. I have also tried just touching the shellplate without the 1/4 turn and same results. Factory non-crimped ammo does not result in backed out primers. I am using AA2230 with cci-400 primers. Thanks guys - J
I have also polished up the decap pin/neck expander with a dremel, buffer wheel, and some jewlers rouge. It feels very slick and most of the maching marks are gone now. Could this keep my brass from growing, or is it better to still use neck lube?
Thanks guys - J
