Corn Cob media stuck inside casing

I may have inadvertently loaded some .45 ACP that might have had flakes of corn cob media stuck to the inside wall of the casing. I was confident that all the casings were clean and clear but when I was doing a powder load check on the scale, I notices these white flakes and I knew exactly what I had happened. Will these flakes cause any problem with the load and firing of the powder or the performance of the rounds?
Using a 230 gr FMJ round with Bullseye Pistol powder about 5.4gr of powder.

As long as the primer pocket wasn't blocked, everything should be fine. That usually only happen when you remove the old primer first, then dry tumble (to clean the pockets). That's the recipe I use as well for the 45.
BTW, this is the Mr. Bullet feeder section, this should have been posted to the handgun section.

The presence of corncob won't make any changed to the pressure or burning rate of the powder.
