i have a RCBS 7mm-08 die i have been using for about 18 years. i noticed today while resizing some brass the die is no longer resizing the neck.i ran the brass all the way in until the handle of my press cams over. i also noticed the expander ball is not dragging coming out. I can take a 7-MM bullet and push it in by hand on my resized brass with no pressure. is my die worn out?

how many cases do you think you have resized with that die/
Try some diffrent cases, once fired, that will rule out over worked brass, the case neck could be springing back.

Agree with Hivelosity. I would try changing brass first.

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.



What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

Any chance you got some thin neck turned brass or got the expander ball swapped by accident?
Or just picked up a .308 sizer by mistake.
Not that I would ever admit to doing such a thing.

My Hornady Pacific full length sizer die in 7MM-08 measures .305 inside diameter for the neck.

If your's is really that worn check to see if a .308 bullet will fall through.

Brass is so much softer then steel I can`t see how one could ever wear out a die, especially to the point that one day it just quits working. Even with dirty brass, wear should show before this point. There must be another problem somewhere.
Have you double checked the bullet diameter? Maybe they are mismarked .277 for example.

Joe,
I thought of that later but was too lazy to come back and metion it.
I have and old RCBS 32-40 die set that must have been used for 40 years and 10,000's of thousands of rounds that is just nicely polished now.
Most dies start out .007 to .008 undersize to begin with.

one thing about rcbs they stand behind there products.
call the other day to order some decapper pins for a new set of carbide dies. dummy here broke the original.
Could not decide which one was the correct pin so I talked to a sales rep and she sent me 5 new pins and a new stem no charge and no shipping cost , how good is that.

They will send you a new die and all will be well. You may never know exactly what their findings are.
I had a .25/06 that did not shoot as well as expected. I finally realized that the bullet in the loaded rounds wobbled about .030 when rolled on smooth flat surface. I check the seater die in a lathe and the seater stem had about that much run out. RCBS asked me to send it back with some of my brass and bullets. About 2 weeks later I got my brass, bullets and a new set of dies back. Two of the cases had bullets seated in them and they had no wobble. The new seater had no wobble in the lathe.....
And the bullets had no wobble when loaded and shot at a target. The rifle went from about a 1.25" group shooter to about a 3/4 inch group shooter.

Interesting that you die wore out.
I just bought a RCBS 7MM-08 die set. The neck measures .303 inside diameter.
