Gotcha. However, if you are not getting all the residue out of the primer pockets, they are going to be difficult to prime. I don't know if you are currently doing that but, I take it you aren't for the obvious reasons they are hard. You gotta do it though. If you get the primer pockets cleaned out well, they'll prime much better.
I am just trying to help. I may be assuming something that isn't so. If I am, just ignore it. If I'm not, do it and you'll see why it is necessary. God Bless

Cleaning primer pockets is
NOT needed. You can load any cartridge with a boxer primer that has NOT been crimped
without cleaning the pocket. OCD reloaders insist it's necessary though. Many blind studies have been conducted, cleaning versus not cleaning, no difference in; velocity, group size, or Standard Deviation, (SD).
However a primer pocket
uniformer will only cut the bottom of the pocket square and to a uniform depth. It usually will also remove the fired primer residue at the same time. It does nothing to the inside dimension of the pocket,(circumference).
