Hey! So I'm trying to put my 9mm powder coated bullets through my sizing die and my bullets keep getting stuck. My bullets measure .358 and I have a lee .357 sizing die. I lubed the die and still get stuck bullets, what am I doing wrong? Should I get a .358 sizer instead? Thanks!!

Strange. I use the Lee .357 sizer for my 9mm PC bullets. They measure .359-.360 after powder coating and whistle through the die like grease through a goose.

I've found that sometimes with NOE dies that the first few bullets need a thin film of oil to make the sizing easier.
They do discolour more than other dies, so perhaps there is a fine coat of rust developing between uses.
In some cases I oil every fifth bullet.
Perhaps, this is the case here. I have used Lee dies in the past and have had the same problem a bit.
Lee doesn't give you the range of diameters that NOE does.
I would carefully measure the size of the hole compared to the bullets diameter.
A large diameter reduction in a hard bullet, takes a lot of effort.
 
Slug may have hit on the bug-aboo that is working against you, that being lead composition, is it a very hard cast bullet or is it just a somewhat softer WW sort of composition. I'm like Augie, I've sized hundreds of WW composition 350-400 grainers with a lot longer driving band area than you pistol slugs will have, down 4 thou or more. I size dry and they go thru readily.

I have sized a few commercial hardcast after powder coating and do notice a considerable difference in handle force required to push a slug thought the press, even at a thou or two downsizing.

Nothing I haven't told him over P.M ...
 
All my cast and pc bullets were done using 356 dies and a 357 resizer. If your bullets are 358 and then you are pc'ing, you are going to have problems like stripping of the pc
 
Hmmmm, it is wheel weight composition. 5 will go through easy then 1 will get stuck bad... I ended up skipping sizing and loaded about 200, just got back from the range and they were very accurate and all was well! I still want to get the next batch sized though!
 
Just solved it, it needed A LOT of lube. I lubed and greased the die and bullets like crazy, and it just kept getting easier, now it's running super smooth without lube! Thanks everyone!!

I have yet to have a sizing die strip off the powder coat.
I have resized several thousand 285 grain powder coated 0.369" bullets to 0.368", 0.367" and 0.366" with no stripping of powder coat.
I have found that an oily patch run through the size die when pushing a bullet through gets stiff helps a great deal.
