Shoulder collapse

Went to the range today and tried out my second series of re-loads for my 6.5 mag. Got home, lubed them with One Shot, let sit a minute or two, and began full length sizing. After a few cases, I noticed a "ring" just above the shoulder on one casing. I payer it no attention and continued, sizing two more cases. After the 3rd ring I decided to inspect. I found a small indention in the area between the shoulder and the beginning of the neck. Checked the other 2, same thing.
I remember reading too much lube could cause this, so I wiped clean with a towel, and re-applied with less generosity. The cases "vibrated"up, and down, in the FL die in what appeared to be, and obviously was, a "lack of" lube situation.
I tried re-setting the die, same result. Taking of apart and cleaning, same result in both re-set scenarios.
These cases (6.5 mag) are somewhat hard to come by and I'm at my wits end which was a short trip anyway due to my '06s performance at the range. Please advise.
Here are some pics if this helps.

the case on the bottom is one of the victims recently FL sized.

the same 2 cases, except this time the victim is on the right.

same victimized case, different angle.
If it helps, I'm using Redding dies.

I would recomend try spraying some lube on a cleaning patch. Then rub your finger tips across it. Use your finger tips to lube from just below the shoulder to the base of the case, and then try sizing it.

Too much lube didn't cause that. Too much lube causes dents in the shoulder. Decent pics can be seen in the ABC's of Reloading if you have that book.

Looking at the pics, the only thing that comes to mind is that if the cases are too long they could be hitting the end of the sizing die and causing the squishing. RCBS X-die by chance? If so, read the instructions and get the die set correctly.

They're Redding dies Jeff h. Instructions say to touch shell holder, then, screw in an additional 1/8 to 1/4 turn. I tried both of those.
M&p, I will try the patch and lube technique tomorrow, Thanks guys.

Did you lube insided of the case necks by any chance? It could be from the expander pushing down on a dry case neck. Lube inside the necks with a Q-Tip, or a pipe cleaner with a touch of lube on them.

Oh and what he said is correct those are not lube dents.

Also you might try backing the die off to touching the shell holder, and then back about an eight of a turn or so. If they are going back into the sme rifle that fired them it should not pose a problem. A lot of folks use the FL die to barely move the shoulder back, and close the neck enough to get bullet tension.

Make sure to clean your die also. An accumulation of lube and gunk can mess you up. I clean mine each time with an aerosol gun cleaner then clean it out with a patch until the patch comes out clean, just like cleaning your rifle. Also use a flashlight and visually inspect the die inside.

I also just use a touch of lube on my thumb and forefinger to lube cases. I don't use the lube pad technique anymore.

I'm pretty sure I sprayed well inside. But, to be sure, I will use a cotton swab and apply after a neck cleaning brush has been run through.

I forgot to emphasize a SMALL amount of lube inside the case mouth. The case mouth should be checked for cleanliness as part of your cleaning and inspection process.

Okay, I WAS in bed, but felt the need to try some recommendations.
Another case, cleaned neck, applied lube, applied lube with swab in case mouth........same result.......3 times! "buckled" shoulder. But only in one place on the shoulder:confused:. Tomorrow, I will try backing the die out. I'm tired, my pride is severely hurt, and I'm steadily costing myself money. Good night, and thanks again for all potential remedies.

Clean the die real good with a good solvent. I use break-clean. Remove the expander button and decapping stem. Lube a case and re-size, if it continues to buckle the case call Redding.

Are these Redding Bushing Dies?

Steve, I cleaned the die very good and repeated the earlier results. They are not bushing dies. I did not think about resizing without the decapping assembly, that sounds like a great idea. :thumbup:
Will try that when I get home from work. Thanks.

no place to go

There is brass flow and stretch, or is it brass stretch and or flow? What I do know is I have never found skid mars on a case that has been fired multiple times.

I have tested cases for work hardening, not something that a reloader would do but in my efforts I have turned cases into accordions, or cases that resemble bellows. And I have cases that collapsed at the shoulder/case body juncture, the cases that have collapsed (as in the picture furnished by Jason75979) were caused by bad habits, or by following instructions on the Internet as in "all you gotta do to form a case is lube the case then take the full length sizer die to form a new creation.

Again, I am the forming die fan, the forming die shoulder is not as abrupt/radical as the full length sizer die shoulder, the forming die is case friendly, in the 'big inning' case forming and case sizing was case friendly, all had long tapered bodies and long tapered shoulders, there were no shoulders with steep angles. Then came Ackely and methods and techniques changed, not re loaders, just the methods and techniques, re loaders continued to attempt shoving brass around a steep shoulder, if the brass will not flow around the case body/shoulder juncture and the shoulder/neck juncture when sized the case squats and or compresses and folds, anyhow, I use the companion tool to the press, the feeler gage as a transfer/standard, because? I know the length of the chamber before I attempt sizing, and when forming long magnums to short magnums I use forming dies that will allow brass flow nicely around corners, THEN! there are donuts, the results of more bad habits.

Then there are the cute little dies that lock onto the neck leaving the brass between the head of the case and shoulder neck juncture no place to go when the ram is raised.

"The cases "vibrated"up, and down...." chatter, locking up, skidding, sounds like the case is locking to the die, this could make it more difficult for the brass to flow around the corners, neck and case body junctures.

Most sizing problems I've encountered people are usually using a spray lube, I think it's best to use a case lube applied either with your fingers (I use RCBS case lube in the tube), or use a pad to roll it on. Which ever method you use It's important to not apply any lube on the shoulder or neck! William

I'm still a little new to all this and for some reason having trouble understanding what you're getting at???
BTW, I removed decapping assembly and still had issue. So next, I revisited my thread from a while back about "bumping" the shoulder. I then tried (as suggested by F. Guffey) using a feeler gage and sizing .002 less. Hmmm, success! No more dimples in the shoulder area and the case still chambered easily.
