Occasionally when I apply too much case lube before running the case into the sizing die I get a dent in the shoulder area.

Is that a problem or can I go ahead and load up that dented case?

Not a problem. The 55-60,000 psi when it fires will take care of the dent.

Allen,
I wouldn’t worry about it. The case will fierform back to the shape of the chamber.
Bill

make sure it chambers first.

Thanks,
I always was curious about that but just threw away the case to be on the safe side. Now I know better.

Happens to me on my 300RUM. Sorry if this is a semi-hijack -- could it be the die? I really dont have it happen w. any other cases and I reload 14x calibers.

I guess a die could have impact. The dent is lube being TRAPPED. I've found shoulder angle and length have an impact. You can also have lube that is left in the die. So a good cleaning might be needed. Several years ago I switched to Hornady Unique lube. Just a quick twist of the case between the LITTLE lube on my fingers and off I go. I tap my finger to the lube and pick up enough to lube 6-8 cases. A little goes a looooonnnnnggggg way. I will use a touch of mica inside the neck every few cases. Imperial was is another good choice. I just found Unique as good and half the price. I put NO lube on the shoulder or outside the neck. A large number of my cases are wildcats with minimum taper and 40 deg shoulder and no issues. I can't remember the last time I dented a shoulder.

Some Dies come with a "Lube Vent"(a small hole) that goes into the Shoulder portion of the Resizing Die. It can get clogged and create a Dent. But it makes no sense because it is easily cleared with a small piece of wire. You would think there is enough Pressure during the Resizing to push the Vent clean.

Anyway, Lube getting onto the Case Shoulder is what causes the problem. When you roll the Case across the Lube Pad, just don't mash it into the Pad.

Clean the Resizing Die and look for the small Vent. Once it is clean, give the inside of the Die a shot of any kind of spray lubricant to keep the Rust away.

It happens to all of us.

I have had occastion where a dent in the case has changed POI when shot. I think it may be due to increased pressures caused by the dent.

If you lube by hand, just swab the lower half of the case. I use Hornady's beeswax lube on my 300WSM cases, and do just the lower half. That is where the real pinching is. If you've ever stuck one and when you pull it out, you'll see the galling on the case right down toward the bottom. When I resize hundreds of .223Rem cases, I use a very light spritz of Walmart cooking spray (cheap-- $2.00 a can), and then I roll them around and tumble them through my fingers until the whole case has a very thin layer of oil on it. They resize just fine, and clean off quite easily in hot water and dish soap. Been doin' it like this for about five years. Never stuck a one...

Possibly a concentricity problem as well..

I do the same with Imperial sizing die wax, keeping it FAR away from the shoulder.
I do use Powdered Graphite inside and outside the neck though. Best combo I've found in 62 years of reloading.

I have never seen an accuracy problem caused by a dent in the shoulder. I do have trouble seeing how a dent would raise the pressure. It will blow out same as the neck and body. A concentricity issue would be eaiser for me to grasp.

Me too.

To look on the bright side, I'd rather have an occassional oil can than a stuck case.

Just keep your dies clean and use Hornady One Shot. Have loaded about 10k with that stuff with no problems--not one.

A set of .223 dies I purchased some years ago had a teeny, tiny piece of kak stuck to the shoulder. Sized around 50 before noticing it as a dent on the brass. Shone a torch down the die and there it was. A WD40 bath overnight softened it sufficiently for scraping with a lolly pop stick. Dunno what it was but the dies were affected none the worse... They were Lee btw
