Sizing

i used rem oil to clean a new die here a few months ago before i used it... wiped it all out good and lubed the case with imperial and sized it... had to order a stuck case remover tool to get it out...lol ...last time i will do that...lol... clean mine with alcohol now and put some imperial on a qtip and wipe the inside down before running a case in them...
 
Was using a new sizing die tonight and it was real tough sizing this brass. I am using Hornady Unique sizing lube which I have been using for a while with good results. But this was really sticking in the die upon removal.

Question: Would the sizing lube be less effective if it was warm, high 90s today so it had a little liquid on the top? I just mixed it all up and went straight to sizing maybe I should have stuck it in the frig for a little while.

Now keep in mind as well that this is a new die and it seems to be sizing tight like minimum SAMI tight.


Most likely its not but it sounds like a small-base die and you are sizing pre-fired brass from a particular chamber.

The fired cases are coming from a Proof Research chamber, the die is a standard Forster FL die.

I have been using a Redding full length die and a Hornady case gauge and nothing coming out of the Redding fit in that gauge. The ones coming out of the Forster do fit the Hornady gauge. I also have a Wilson case gauge and cases coming out of both dies fit in that gauge.

The Forster is absolutely a tighter die than the Redding, funny what a couple thousands of an inch can do. I'm learning quite a bit about dies this year.

The initial reason for changing dies was to get a larger neck diameter coming out of the sizer, I then run a mandrel through it to get the finished size I want. It "finally" donned on me yesterday that I could do this with a bushing die and still finish it with the mandrel die. Slow learner.
 
I have a Hornady sizing die(30TC). I only shoot the rifle on elk hunts, drew a Wyoming tag. Started to prep some 1-2 fired brass. I had cleaned the stored(3years) die with brake cleaner, pulled a clean rag through it a couple times. Looked shiny, and clean. One shot lube the die and brass, let dry. Sizing is spot on, brass is not scratched But die/brass feels and sounds rough. Cleaned and looked again and relubed the die, same rough feeling and sounding. No marks on brass. Brass is sizing correctly and consistent, brass length not changing. I may have to send it to Hornady for a look. Don't remember if it sounded and felt like this 3 years ago. Only Hornady die set I have, my Redding and RCBS don't feel or sound like this.

Your chamber is the best gage, also imo name of die
manufacturer means very little compared to how well it fits your individual chamber.
 
Final Update (I think)
After all of the comments and suggestions I went back to square one.

1. Cleaned die with Ed's Red type cleaner (I think this is what I had used before)
2. Flushed out with Carb cleaner
3. Sprayed the entire die with Hornady Gun Cleaner and Lube
4. Sprayed the inside of the die with Hornady One Shot Case Lube
5. Applied Hornady Unique case lube heavy to a case and started to work it into the die
5a. Add more lube work into the die further
5b. Add more lube work into the die further
6. Did this routine for several cases until the cases started to go into the die easier like on one or two strokes of the ram. A lot of shoulder dents from the lube. I could do 3-4 cases and then needed to wipe out the excess lube.
7. Started to gradually reduce the amount of case lube until I am now down to a normal amount and am not seeing shoulder dents.

After about 4 hours and a "lot" of cases I think I have this die working as it should. I'm sizing to 1.553 and I still get odd ones that will size to 1.551. Brass??

Thanks everyone!

I have been using a light vis petroleum oil for about 20 years. Pet oil is always the perfered lube for small and large equipment. I. Don’t know why people think they need something special made for resizing brass. I worked in research for a petroleum co. For 20 years. About 5 years ago I bought a qt. Of petroleum based hydraulic oil at auto zone. Couldn’t be smoother. Why are some many people posting about lube problems on this website?
 
From Forster FB page:

If you purchased a 6.5 Creedmoor Full Length Sizing Die marked "FORSTER 6.5 CRDMR FLS-Y", it may be three thousandths undersized.
You can check by inserting a fired case. If it goes most of the way into the die, then you received a perfectly good sizing die. If it goes halfway or less, the die will need to be replaced.
Please contact our office by emailing info@forsterproducts.com if you believe you have received an undersized die. We apologize for any inconvenience.
 
Your chamber is the best gage, also imo name of die

Spot on in my arena. Before I spin up any barrel, I have a
chamber cast done. From there, I choose my FL die and do
the same. Most will be in the lathe getting honed to my needs.
For problem sticking, I have not found anything better then
Lanolin. If lanolin does not work, that means you are about to
pull the rim off your case. Been there.....

I have seen that as well and sent a picture of this die with case inserted to Forster. Their Tech team deems this to be a good die and not in the undersized lot. If this is standard I would hate to run into one of the undersized ones, be lucky if the case would even enter the die.
 
Many new dies have a dry film coating to prevent corrosion and most dies tell you to clean the die with a bore solvent like Hoppe's No. 9.

You cleaned the die with carb cleaner and turned around and applied two forms of Hornady "DRY" film lube.

Clean your die with carb cleaner, Hoppe's, etc, and use your Hornady Unique and you will be fine.

The first time I used Hornady One Shot I did not clean and remove all the old case lubes from inside the die and had stuck cases.

It's not the Forster die, in the video the photo below was taken from the Forster die had the best inside finish.

User Instructions for the Bench Rest® Full Length Sizing Die*

Clean the Die
Clean die inside surfaces using a cloth patch saturated with guncleaning solvent.

5.0 AFTER USE
Oil the die with good quality gun oil before storing die until the next use. Clean the inside of die using a patch with gun cleaning solvent prior to sizing each subsequent batch of cases.
able to dissolve other substances.


I don't believe Bore Tech Eliminator is a good choice for cleaning new die since it's water based and might not remove any petroleum based preservative in the die. Also, C4 can leave a "sticky" film if not completely removed. Hoppe's or a similar solvent would be a better choice.

K22, you must be almost as smart, good looking and modest as I am. ;)

Am I missing something? Are you sizing a fired round .295 neck down to .285? Sounds like quite a bit of neck tension.

Fired at .295
Sized to .285 (Would really like this to be .288)
Mandrel to .2895
Loaded to .2915

So about .0015 - .002 neck tension with a lot of neck work to get there.
