Neck Sizing loads taken apart

[Guest]

I have some new Rem Cases for the 300 RUM that I pulled the loads apart. My question is, can I remove the primer pin from my Forester Re-sizing die to just re-size the necks safely without disturbing the primer?

Also, I have noticed the Forester Re-sizing Die leaves the casing with better neck tension verses using the RCBS Die. Anyone ever experience that before?

Thanks for your input,
Don

You can remove the pin, but easier still is to adjust the stem up so the pin won't touch the primer, but the neck still gets resized.

As for your better results from Forster, it is likely better tolerances, but it could be as simple as one specific die being a closer match to your rifle chamber/neck than the other.

Dubyam has, as usual, steered you right, Don. Of you can simply pull the spindle and resize.

Thanks to both you guys. I appreciate your input and expertise.

Forster makes better dies than RCBS. I have used RCBS for 50 years but Forster is better and makes more accurate handloads. I have been gradually converting my sizing dies to Forster for the last 3 years.

If you are using Forster dies, you may not be able to just raise the depriming pin and size. The expander ball is located high in the die and that could cause crushed or stuck cases. Just remove the pin.Rick.

You shouldn't have to resize the necks

Just seat a new bullet

 

[rick smith]

Neck tension will be different if you don't size them.Rick.

Have to disagree with you Woods. You are working the brass both when you seat a bullet and pull a bullet. The brass takes a certain set and the tension changes.

If these are virgin brass I'll bet he'd be fine reseating into those casings. Check the inside of the case mouth and see if its at least. 0025 under bullet diameter seat away if it is.
I've collect pulled alot of bullets on virgin or factory casings and they keep plenty of spring to seat w/o resize.

I can tell you there is a difference in neck tension when you pull bullets, at least it's my experience.
For me there's no question, I have to re-size the necks. I can also tell you my 300 RUM has improved accuracy since using Forester Dies too.

Rick,
Thanks for the tip. After all the good input I'm going to remove the pin. Actually you are correct the expander ball is high in the die, I forgot that.

Thanks,
Don

After pulling seated bullets in a .308 caliber, the ID of the neck will always return to .306"

ALL the cases will have the exact same ID and be very consistent

Have to disagree with you Woods. You are working the brass both when you seat a bullet and pull a bullet. The brass takes a certain set and the tension changes.

+1 especially in a gun like the 300 rum. You could easily cause setback with the recoil at which point accuracy will change as well as increased rick of damage to the firearm or your self. Not worth it in my eyes for 5 minutes worth of work.

In my tests, it doesn't matter what the ID of the neck was before seating the bullet, the neck will always return back to ~.002" below caliber

So if the necks have sufficient bullet grip and they have all just been sized by the bullet, why do you need to resize? Are you saying that a greased up expander ball and reworking the neck brass twice more would be better sizing than the full shank of a bullet?

Here are some pics showing 3 different ID's on a 375 Ruger case

NEW CASE ID - SIZED WITH EXPANDER REMOVED

What happens if you seat a bullet, pull it, and measure, then repeat and repeat again?

 

[woods]

Always returns to ~.002" because of SPRINGBACK

I compared a casing that was pulled apart and one that was re-sized with the pin pulled out of the Forester Die tonight. Casings are once fired Remington Cases.

I could feel a substantial difference in neck tension while seating a bullet in each of the perspective cases. The pulled apart cases seated a bullet with to much ease for me, while the re-sized case had the tension I usually experience while putting loads together with great range results.

While all the comments are appreciated I will be re-sizing any cases I pull apart in the future.

It took me all of 40-minutes to re-size 20-cases that I pulled apart, then cleaned them up. Now ready to reload at a later date.
