Wrinckle neck's

[coldboremiracle]

So, I hope I'm not the only one who occasionally gets a wrinkle in a case neck, or a dent in a shoulder (either too much lube or some other thing).
I was wondering if you guys just shoot them out, or throw em away or what? I usually just shoot them with the rest and have never noticed a difference, but I haven't paid alot of attention either. Has anyone else ever checked on that?

If they are small dents, I just shoot them. Wrinkles get tossed.

if its a 1000y load, toss em, or use for sighters. If your not into precision, then shoot them.

Unless the case is buckled and won't chamber properly, I just shoot them. Funny how the dent or wrinkle just disappears.

I used to mark them so I could see if they'd fail any sooner than "undamaged" cases but I couldn't see any difference in life.

As for "lube dents", most of the newer dies have a "relief hole" that not only lets any extra lube escape, it also lets air out which in itself can make a fair sized dent. Also relieves vacuum for easier extraction of the case from the die.

I've ended up drilling my old RCBS and Redding Dies using a carbide drill bit. Just a small hole into the shoulder area.

This is typically what I do, set them aside for something different.

The last 200rd run of 308 I did the first 4-5 had dents from too much lube. I had always just shot them and reload as usual but I decided to try shooting one in a five round group with non-dented cases. The four non-dented rounds of each group were about .7 MOA apart at 110yds. The fifth (dented) shot opened each group to about 1-1.1 MOA with a random positioning compared to the other four shots.

There is a difference in my experience as I am usually averaging about .6-.7 MOA at that range with my 308. If I get a few like that again, I'll take my Chronograph and see if there are any effects on muzzle velocity.

Re: Wrinckle neck's

I guess, theoretically, dents caused by excessive lube could reduce internal volume and affect velocity and therefore, velocity?

A wrinkle in the case neck; I am unfamiliar with, but it sounds bad? Could this be when the case neck clips on the expander button on the upstroke and causes a crease on the edge? That could affect accuracy, pretty sure about that. I think this is caused by a press that is not vertical and a shell holder that is a little sloppy? Maybe? If so, you have to carefully guide the case until it is past the expander.

shoot them for practice, the dents will get fireformed and the brass will look good again.
