Neck split

[H4831]

If I may be so bold as to interupt with a brief hijack:


I had a similar question about a casing. I overdid it with this one when resizing, and she buckled around edges. Obviously it's only one piece, so I'd toss it in a heart beat, but I'm still curious from a "common practice" sort of side of things.

Would you reload this?

I most certainly would and shoot it at, or in, any type of shooting.
The dents make no difference, whatsoever, to the efficiency of the reload.

I have had those dents on occasion, most notably with 7 X 57 brass. It seems to me that the case necks cracked on firing, for some reason, right where the dent was.

As Ganderite stated, the dents are caused by too much lube on the neck and/or shoulder of the case when sizing. The case will like any other case fired in that rifle and it will not crack because of the dent.

So... Can you elaborate a little on that? What exactly's happening with too much lube? It's sealing around the neck, and a bubble is getting trapped? Is it just an air bubble that forces the brass in like that?

If it were me I would cull the split neck cartridges and prepare the same number of alternate cases and pull the split neck case bullets, transfer the powder to the new cases and reseat the bullets. . Why fool around and risk chamber and throat corrosion, bullets not tight in the case neck, whatever else. . Is it worth it with so little effort to get it right?

The lube has nowhere to go since at the end of of the stroke, there is a seal formed between the neck and the shoulder as it is being sized. The remaining lube on the neck has to take the path of least resistance so it buckles the case and pools there. Ugly but harmless. Since I switched to using a lube pad and rcbs case lube, I hardly have it happen anymore.

I load those dented cases. It is caused by too much lube on the shoulder. It is nothing. I have seen factory ammo with much worse defects.

It will have zero effect on the fired shot and will iron out from the pressure of shooting.

BTW, your case mouth needs to be champfered.

This!

Weird. I used a lube pad too. It was the first shell into the die. It probably had a touch more lube than the others, but certainly not enough to have filled all those dimples.

Since I dry lube case necks inside & out, and never get any lube on the shoulder area of the case, I do not get
those ugly little dents any more. But when they used to happen once in a while, firing them ironed out the cases
just fine, with no effects on further reloads with the same case. D.

I use Lee resizing lube, its wax based and it eliminates dented cases which is a problem with oil base lube. You can apply it with your fingers.

I just got done putting a dent in a case that looks about exactly like the picture! It was the first case into a new Redding die. Figuring the die would be machine shop dry, I thought it should have a wee bit of lube on the neck and shoulder. Anyone who has used Imperial sizing wax knows its next to impossible to get a "wee" bit of the wax on anything. When I used an oil lube on a pad I never got the dents, because only the body of the case rolled on the pad, thus no lube on the neck or shoulder.

Thats what happened to me, I was loading for a 7-08 with a new redding die and I got the same dent on the shoulder. I had never had dents until then. I was using oil lube and the pad.
