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

Cassidy

Thinking about starting to measure primer pocket depths then uniform my 30BR primer pockets; at least to test if this will improve precision on target. What are the most reliable, precise and reasonably cost conscious tools to measure primer pocket depth then uniform the depth?
 
Since you are cost sensitive, as am I, I'll break from the pack and observe that a standard machinist depth gauge does exactly the same thing as the above tool. Go to shars.com and you'll find something for a lot less money that will work just fine if not better, just be sure that the probe diameter is small enough to fit in the primer hole. You can also use the back end of a standard caliper but a real depth gauge will give more consistent results. I just use a standard hand held primer hole cleaning tool (mine's made by Lyman I think) but I put one of those bushings on the bit that's made for putting onto a drill bit to control depth of cut, probably available at your local hardware store. It won't impress anyone but it works.
 
I use "Hollands". Initial depth checks I use a Starrett depth gage
from one of my Kennedy's.......Note.....take 5 cases and swipe the
bases across some crocus cloth to make sure they are flat. You
don't want to measure depth if you have a rolled over rim edge,
or any other sort of damage or dings.....

I think the Holland is great. It cleans/cuts the pocket to the exact same depth every time and I use it between most firings to clean and track changes in pocket depth.

I use a 21st. Century uniformer set at .126 to just touch the bottoms and lightly clean the carbon out of the pockets on my bra however for the nationals I reframed from even cleaning pockets and went straight to tuning and loading as they were, with no detectable lack in performance.
So I guess the bottom line mirrors Jackie’s question to why mess with them at all ?

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 have no idea, but along with seating primers to a light crush by feel neither cleaned or light carbon left in the PP seemed to make any difference.
 
I have the 21st Century as well as the very budget Hornady. It's a little harder to set and make very small adjustments (this is where the 21sy Century comes in), but it gets the job done just the same. For one box, I found the deepest pocket, set the Hornady to that depth, then turned the rest to match. Another box I set a desired depth with the 21st and ran the box. There's a 0.001" difference between the boxes and I can't tell which one shoots better.
