So, One of the oh so many times I wish Dad were still around... OR, maybe, that I had listened a little more closely to what he had to comment on...
SIL bought a "tricked out" heavy barrel Rem 700 in 300 Win Mag (never been fired, the guy built it and then was too scared to shoot it) and 60 rds of Corelokt 180g - which the gun DOSEN'T like (2.5" groups at 100yds).
Off to the reloading room.... Dad just happened to have left me a set of RCBS 300 win mag dies (why we have? IDK... we've never had, or loaded 300 win mag before, that I am aware...) ... but, they are FL...
1,2,3 cases sized and decapped, then the decap pin broke on #4 - replaced pin and then - the stupid case stuck...
Got the stuck case out (after destroying the exp-decapping rod - swapped another from the 30-06 dies)
#5 decapped and sized fine, then #6 stuck the case... by now, I have finally found the stuck case remover ...)
Well, in the past, I have had no problems on the rare occasions I FL my 7mm RemMag brass... what's up?
Could there maybe a problem with this set of dies? Or, the case lube I'm using (RCBS, that we've always used and never had problems with)? OR, should I just order a set of neck sizing dies and be done with the problem?

Good to hear from you, Paul. While I really do not have much to offer as for help with this issue, I did just want to say hello and express how much I miss your Dad's comments and threads.

I do have dies for both the .300 Win. Mag. and the 7mm Mag., but I have never loaded for either one. But I have read where many prefer to just neck size if possible for the belted magnums in order to prevent case separation problems. I am betting that someone will likely give you some better input shortly. The site is a bit slow, but there are still a good many of us still around.

Sometimes you have to lube inside of case
necks. I use graphite or mica. This makes
sizing a lot easier.

Thanks, Ham... while I don't have the time to spend on the 'net like dad had, I still spend time in the reloading room... currently helping a friend of my son work up a load on his 300 weatherby mag, and trying to make a gnat shooter out of my .308 with some WC844 (don't really think that is going to happen, but I have ~24lbs, and have loaded enough .223 to last me several lifetimes.. LOL)

CDE... now that you mention the lube in the case neck, I recall us doing that for something in the past, seems we had a shallow can of some white powder we dipped the necks in... I'll look and see if I can find it and try before I spring for a set of neck dies - in a 14x32 building that is probably 60% devoted to reloading, it may be a tough search to find that little can...

I don't think it's the neck if you're getting stuck cases.   Not sure if
the lube has gone bad on you or not.   But, if a case sticks it most
likely is the lube you're using.

Years ago I had a customer that I loaded three different
Weatherby magnum cartridges for. Case life was not
exceptional, but in order to process them I did the
following:

1. Tumble them to being very clean.
2. Using a bronze cleaning brush, place some Lee case
lube on the brush and clean/lube every case. Making sure
enough lube is inside the neck.
3. In a plastic tub [ice cream type] place a couple
nickel sized blobs of Lee case lube in the tub and drop
in a few dozen cases and tumble freely.
4. Remove lube cases and set them upright to dry.
5. Inspect the dies for old lube and dirt. Best to run a
fitting bore mop up into the dies and clean them.
6. With dies clean, run another clean mop up into the
sizing die with a very light coating of Lee case lube on
the clean mop.
7. Resize and deprime cases slowly watching for excessive
resistance when pressing the ram handle. Back the die off
slightly if too much resistance is encountered and try
again.
8. Once sized, place cases in another plastic tub filled
with hot water and dish washing liquid. Clean cases and
rinse freely with hot water. Then set aside to dry or
heat in a small oven at 200F or so until dry. Usually 30
min will do.
9. Tumble again. Yes, this will clean the primer pockets
and remove all traces of the case lube.
10. When clean, trim and process cases for final stages
of loading.

I abandoned the syrupy case lube decades ago in favor of
the Lee sizing lube. It's wax composition and drying
ability combine for zero case dents encountered with
liquid lube and doesn't impact the shoulder of the case
where sticking often occurs via a vacuum that can form
otherwise.

In the years that followed, I have used the above methods
to size and process all bottleneck cases and those that
require case lube. In over 40 years since employing this
method, there has never been a stuck case or difficulty
processing cases of any sort. The consistent coverage of
case lube via tumbling and then sizing fully dry lubed
cases has proven itself continually without fail.


Hope this helps. And I'm just up the road a piece near
Athens. Ya ever need an old man's help just shoot me a PM
and we'll get 'er done.

Ya - the 300 Win mag case isn't particularly difficult to load. And it's got tremendous accuracy potential!

Clean the brass, clean the dies.

Apply adequate lube on the outside of the dies - you'll know it's too much when ya get "dimples" on the shoulder area of the brass.

Apply a dry lube, like graphite to the inside of the case neck. Just a tiny bit will do wonders.

That ought to get ya going just fine!

And heck, invite ol' Wade to come help ya out in person. He's got some great knowledge!

BTW - I went to "wax" type lube for all my handloading long ago as well. It's real easy to apply, and to clean off the cases later.

I have been using Imperial wax type sizing lubricant for years and I have had no problems whatsoever and clean up is just a quick wipe with a rag. It is made by Redding I think. I got away from the old sticky type RCBS lube and pad for rolling on the case lube many years ago, but I am sure that RCBS has something better these days. I always had trouble with dented cases using the old sticky lube.

Hornady One Shot worked well for me before I started using Imperial sizing die wax. But I did stick a couple of cases before I figured out that the can of Hornady One Shot has to be agitated really well each time one sprays it or an insufficient amount of lube will be sprayed onto the cases. A friend of mine borrowed a set of dies from me and he stuck a case while using Hornady One Shot because of lack of agitation of the lube in the can. He ended up destroying the die in an attempt to remove the case. He was embarrased when he returned it along with a brand new die.

I have read a few threads about necks being pulled out by the decaping/neck expanding rod when not using neck lube. While I do not always lube all my necks, I do with certain dies that do not have the most gentle expander angles on their expanding rods. The newer ones with a carbide expander work wonderfully without lube.

My guess is the expander ball or the inside of the case neck needs lubricated.
Or the size die could be set just a little deep in the case pinching the shoulder
into the base of the neck just enough that it hangs up on the expander.
Try lubing the inside of the case mouth, and back the size die out 1/8 of a
turn. Make sure the expander/decapper isn't set a tad long causing jamming
the pin/ball into the flash hole.

Thanks for all the inputs...
I don't think the decapper is set too deep - I have it adjusted to where the primer is just barely freed on the full stroke...
After reading the suggestions, I'm to the point of
1)cleaning the die to rid any ancient residue junk...
2) lubing the inside of the case necks (I found the mica today)...
and 3)looking for the can of Imperial sizing wax and giving it a try.

Tomorrow's forecast is rain all day, perfect for some reloading...

So... A quick story of part of my "inheritance" from Dad... It took me almost a week to clean off just 6' of the 12' reloading bench after he passed, just so it could be properly used... he had gotten pretty sloppy in the months prior...
The clean up resulted with a box full of various caliber "mystery" loads that, rather than pulling all the bullets and dumping powder, I thought would be fun for us to fire off at our family Thanksgiving (there's around 30 of us now...)...
Most everything we had could be fired out of Dad's vast collection of Handi rifles, so I didn't bother with digging any handguns out....
We had a great time firing all those rounds off - it didn't matter if you hit what you aimed at, it wasn't expected, we were just "makin noise" in memory of "granddad" ...
The last rounds up were .44 mag, and it was my turn to shoot those last 10 rounds... bang, bang, bang, bang, BOOM... ... my son was sitting next to me, and we looked at each other, as he said "uummmm???", as I was thinking "good thing it was in a rifle and not a pistol, or I would probably be 'sportin a broken wrist right now"...
Needless to say, I've pulled those last 5 rounds...

With that many cases sticking, I would look at that sizing die. I once
had an RCBS sizing die for the 30-06 that would stick a case EVERY
TIME regards of how much lube I used. Got so mad I stripped off every
potentially usable piece and threw the body away. I know, I should
have sent it back to RCBS but I was really P.O.ed as I needed that
ammo literally yesterday.
As far as reloading belted cartridges go, I just ignore the belt and load
them same way as I do rimless cartridges.

The following is a cut and paste of a post I made quite a few years
back. I've never had a problem loading belted cases since going to this
system.
Paul B.

This is how I set up my sizing die for bottleneck cartridges.

1. Take a once fired factory round and blacken the neck and shoulders
with a Magic Marker or Sharpee pen. Some people like to smoke the
neck and shoulder, but I find the Magic Marker/Sharpee pen a bit
better.

2. Carefully lubricate the case.

3. Loosen the lock ring on the sizing die and back off about two turns
from when the die is set to touch the shell holder.

4. Size the case. Note where the marks are on the case and turn the
die down about a half a turn and size again. Turn down some more,
and resize again. What you are looking for is the marks on the
blackening just touching the shoulder.

5. Clean the lube from the case and try it in the rifle. It may chamber
just a bit on the snug side. If so, turn the die down ever so slightly, lube
and size again. Wipe off the lube and try in the rifle. If it slides in as
easily as a factory round, you should be good to go. If not, usually one
more very slight adjustment should fix the problem.

6. Tighten the locking ring for the die and you're done. You have just
set your sizing die up for a custom fit to your specific rifle, rather than a
generic one size fits all guns.

I have a savage 110 ba in 300 Win mag I like using ppu
brass I have reloaded them untill the primer falls out
I only necksize them
U have to careful is every time u full length resize u
push more case around the belt causing a jam at full
stroke no amount of lube would help at that point

I would suggest to take a good look at your once fired
brass to see if there are any swelling of the case 300wm
Is a high pressure cartrage with a relatively thin case

Well, I got a new sizing rod and 50 pk of decapping pins in for the RCBS FL die, and SIL comes over with a new set of Lee neck sizing dies for the 300 WM... so I set up the Lee set, lube the case necks, .... and 1st round bends the decapping pin... He's running the press (has been all along)... Hmmm....
After all the suggestions listed, we used the Imperial sizing wax (finally found - along with a can of One Shot - {now, only if someone could suggest where the remote to the chrony might just happen to be ...}), and lubed the case necks, and re-adjust the FL dies ( I did not do the Sharpie/Prussian blue type adjust, which may have made a huge difference...), only to end up with FL sized cases that the bullets would literally fall inside of,...
To make things move along, I backed off the RCBS sizing die to where it just deprimes, then used the Lee die to neck size (good thing I have 2 Rock Chuckers set up on the grinder stand, one of us decaps from one side, the other neck sizes - I guess I could have set it up in the Lee turret press or Hornady Lock n Load to make it "easier", but, maybe it's just me, - I just seem to have "consistency" issues with rifle ammo on those...)...
We then started playing with some 150g loads using IMR4350 and found a load that produces a little less than MOA groups... just as his shoulder calls "Uncle" ...
Now the M700 has gone to have a muzzle break installed, so "tweaking" the load has come to a halt for a moment (which will give time for the hand deprimer, that I've had my eye on for some time..., that joed got..., to come in, as well as a few extra Lee universal decapping pins to fit it )
