9mm plated round nose getting flat nose

Not really. In your original post you mention 38 RN but your last post says 38 WC which is a wad cutter which is flat nose bullet. I'm not understanding what you got in the plastic bag. I totally agree the dimension difference is negligeble, it's the shape that is the problem. Seems like RCBS should have one sitting on a shelf and with their good reputation would probably drop one in the mail at no charge.

Many thanks for responses in the green bag is what I received when I bought my dies.I agree that they should ship me out one on the shelf sadly I was told to mail in 3 115 grain Bullets and they will make one with the same Ojave quote and 24 bucks I& it would've been a lee die it would be 8 buck so my story continues

Ok here it's is received a lee seating die today loaded approx 100 9mm with ever so light rounds nose flatting closing the trouble ticket out again the shooting and reloading community is the greatest of course IMOHO reditiredin out for now

Check contour of seating plug vs contours of bullet nose...plated
slugs are a lot softer than jacketed bullets.

You could touch up the cup of the seating die with a Dremel,
but a bit of nose-flattening might give a better terminal effect,
if you're hunting.

Agree 100%.
I filled the nose recess in one of my .38 seating dies with some of that steel-impregnated epoxy putty in a clear plastic sleeve.
Has worked perfectly for years.
Also used some of the same stuff to build up the front sight on a percussion .44 revolver I shoot a lot.
Has lasted for years also.
Great stuff.

I have also read here that some people use 38 special Bullets in 9mm and 9 mm Bullets in 38 special they are very close in size to one another.

While the .38 Special/.357 Magnum is nominally a 9mm cartridge, the bullet diameter is 0.357 inches. In the case of the 9mm Luger cartridge, the bullet diameter is 0.355 inches.

Assuming the barrels in the respective guns were bored with those dimensions in mind, using a 0.357 bullet in a 9mm cartridge requires the barrel to draw the bullet down by an additional 2/1000 inch as it makes its way down the barrel. It requires additional pressure to perform this machining operation while the propellant gasses are simultaneously driving the bullet down the barrel. In such case, the powder charge in the 9mm case should be reduced significantly and built back up incrementally while looking for pressure signs.
