So I am hoping to pick some brains and maybe someone else can help me figure out what is going on here. I was going to switch my progressive press over to a different set of dies, but wanted to run them in my turret press just to be sure they were in spec and sized brass properly before doing anything else. Both pieces of brass are Winchester 5.56 brass, both from the same lot of ammo, both fired through the same rifle, both only fired a single time, and both cleaned in a wet tumbler for the same amount of time. I feel this should pretty much negate any significant differences between them.
In the picture, you can see one has a clear ring around the base of it(sized in a Lyman Pro .223 sizing die that it turns out has a carbide sizing insert), and the other looks perfectly normal with just the regular line we see where the die stopped making contact with the brass(this was sized on a Lee .223 full length resizing die). Both cases were lubed with Imperial Sizing Wax(normally use spray on case lube, but since these were just going to be a few one-off things, I just used the sizing wax).
Does anyone know what is causing the ring around the base of the one sized with the Lyman die? It is a physical ring/step/lip/ridge that you can catch your nail on. I don't believe it to be an impending case head failure, because even if I size them through the Lee die first, I get no ring, and then if I run them through the Lyman die, the ring appears(although slightly less pronounced than if they were only sized with the Lyman die).
Does anyone have any suggestions? If I stop sizing at a point where the ring doesn't appear with the Lyman die, it doesn't come close to fitting in a case gauge. In order to get it where it fits in the case gauge, I get the ring you see in the pictures below. With resizing using only the Lee die, the brass fits perfectly in the case gauge(other than needing trimming, but that is to be expected). Really hoping someone can help me out, here.
In all pictures with both pieces, the brass sized with the Lyman die is on the left and the brass sized with the Lee die is on the right.
Edited to add: The ring on the Lyman sized brass is also right at the point where the die stops making contact with the brass, and it feels like my nail catches slightly more going from base to neck than it does going from neck to base.
