What are most reliable, precise and reasonably cost conscious tools to measure primer pocket depth and uniform them?

Old habits hard to break.

If the type of primer matters, and primer seating depth matters, and ignition is affected by firing pin fall, how can a primer pocket full of residue not make a difference?

I didn't use to clean out the primer pockets, in fact, I quit using pins while wet tumbling. One loading session after priming, I looked inside the cases and couldn't see the usual shiny reflection of the anvil. I turned the case over and tapped it onto a piece of paper and got a not insignificant amount (to me) of soot. Then I could see the shiny spot. I thought, hmmm, if the first thing the ignition sees is something a lot less ignitable than powder, how can that not have an impact? So now I use this https://shop.rcbs.com/primer-pocket-brush/ with or without tumbling before resizing. No handle, I just spin the tip in the pocket with my fingers, tap the base on the bench and grab the next case. Takes 5 min per 100.

Personally I would just buy a fixed tool and go to work. If it cuts great, if not then you are good to go. Easy peasy and you didn't have to buy a depth gauge that will probably never be used again.

Even with the best uniformer without measuring...you will leave something on the table. Ive gone through the process too many times.

I think in Bart’s interview he said that the brass grows in the pocket after each firing and that he hit the pockets each time because of that.

The steel is recessed at base as well. Thank you!
You are appreciated!

That is a dead match.
