Tight neck whenís pulling brass out of full length size of die

Hi question from a novice reloader, am getting the odd case which is very hard to pull out of full length sizing die , have annealed cases and still getting the odd one

Is it just lack of oil causing this or am I missing something else .

And will these tight ones be causing accuracy issues
Guns 7mm rem mag case done Three or four shots Norman brass

Thanks

Possibly not enough lube inside the neck? I use graphite powder, buy it from mitre 10,pop it into an old film container with the shot from a shotgun shell, dip the neck in to coat it, you do have to wipe the outside stuff off.

Are you lubing the inside of the neck at all?
Dipping in graphite or mica in one method, but I find wiping my finger on a lubed case then across the mouth of the case leaves enough lube to make a big difference,† even doing it every 2 or 3 cases is enough.

Just use hornady one shot spray lube , normally make a effort to get spray in case neck , might pull expanding ball out of die to clean and lub up , have a gauge on way to measure run out to see if the tight necked brass is getting extra run out or not

Hornady spray is pretty poor quality stuff. Imperial sizing wax is far better.

I never use expanding balls on my dies at all. I remove them when I buy a die and use a K&M expander mandrel to open up mu case necks prior to neck sizing with a Redding bushing die.

Hornady One Shot (aerosol not plastic pump bottle) is excellent lube - for NECK SIZING ONLY. The one and only time I got a case stuck in a die many years ago was using One Shot. For neck sizing I spray the tops of the case from 2 sides but at an angle so spray goes inside the necks. Also you must let it dry b4 running the cases thru the die. Virtually zero cleanup is required once thru the die.

For full length sizing I use either Hornady or Lyman oils (never the liquid Lee water based version) applied via a stamp pad (buy an uninked one front stationery shop). On the cartridges where I still use an expander ball I lube inside the necks with the same stuff on a cotton bud. Quick and easy and effective.

I don't like using Imperial Sizing Wax for FLSizing, too slow compared to rolling several cases as once on the stamp pad. I do however use it for case forming, there is nothing better.

Iíve been reading about the taking expander ball out. But I donít neck turn , i was looking at buying a replacement expander ball for my redding die ,I see they have a floating carbide button kit that might serve my purpose well ?thoughts ?

I neck turn, but you donít need to. You could expand the neck with a K&M expander mandrel (which are simple and pretty cheap), then neck size as usual.

I think neck turning and bushing dies are the single best way to control neck tension and ES, but I admit itís a faff and good neck turning gear and bushing dies are expensive.

I use Whidden dies for all my rifles, including my 1000 yard f-class rifles. Part of the reason why I like their dies is that you can get an expander ball kit for most calibers to play with neck tension. If you go to the web site and look in the decap assembly section, you will find the kit.
Neck turning will not always take the inconsistencies out of the brass, and an expander ball is necessary. That is even true if you use an expanding mandrel before sizing, since spring back will vary from brands and lots of brass. Cheers

Imperial forever. What is the issue with a quick clean after sizing. Your necks are perfect. Isint that what you should concentrate on.

Why wonít you get spring back when using an expander ball? I donít agree that an expander ball is necessary, but thatís OK as itís just my opinion and we donít need to agree.

I just havenít found any benefit in cleaning in trials, other than cases looking nice. Accuracy was the same whether I tumbled cases, or just brushed necks, or didnít clean at all.

I was taught to clean the lube off sized cases, the theory being when you fire unlubed/clean cases they grip the sides of the chamber (to a certain extent), while lubed cases transfer much more pressure to the bolt face.
Nowadays I mainly neck-size using collet dies, so no lube used, so none needs to be cleaned off.

Lube the inside of the cases, polish the expander ball to a better finish and if youíve annealed the case neck, polish the case neck up with some 00 steel wool to remove the blue tint annealing heat marks.

Iíve polished all my full length die expander balls, so donít need to lube the inside of the case necks anymore.
