Who makes a depth adjustable primer pocket uniformer ? I have the Sinclair non-adjustable ones but it does not uniform the bottom of the pockets until the brass begins to move which can take several firings. Thanks in advance.

21st Century
I have an RCBS and the 21st Century uniformer. I like the 21st Century best as it's really easy to make adjustments . . .AND is a hair smaller in diameter, which work better in those cases with tight pockets.
The RCBS one I shown has a locking screw on the side that can be loosened (can barely be seen on the far aright upper side), then that threaded shaft can be screwed in and out which adjusts the height of the cutter.

21st Century tool works perfectly

K&M makes the best of the ones I have tried. The 21st Century looks nice and all of their tools that I have bought from them are top notch.

If it does not uniform the bottom of the pocket that is because the pocket is already deep enough, or maybe too deep. Primer pocket uniformers aren't a tool to just flatten or clean all primer pockets, but they often in fact do that, to some degree or another, if a given pocket is getting too shallow and it gets uniformed, partially, or fully.

I wouldnt say it is trouble but the brass has to move before it will touch the bottom of the pocket therefore not cleaning it.

I use the same RCBS model, and like it just fine, especially since the back is threaded to attach to whatever device you wish to spin it with
Bill, I have a Sinclair primer pocket cleaner and a Sinclair primer pocket uniformer which is adjustable. I rarely use the uniformer because most of my brass is Lapua. I do use it occasionally on some of my old Rem & Winchester brass, to be honest, I rarely mess with primer pockets, unless there is a problem which is extremely rare, especially with Lapua brass.
You are an experienced precision shooter and probably know a lot more that I do, so I offer this only as my experience regarding primer pockets. Also, this is offered in the context my shooting discipline, precision varmint and predator hunting.
Over the past 50+ years like many, I have always sought an edge to improve performance. For many years I just cleaned the pockets with an RCBS cleaning tool to remove the gross primer residue. I still believe this is important to obtain flush seating (slightly below the rim of the case).
Seeking improvement, several years ago, after reading many articles, I purchased the Sinclair pocket uniform tool and started uniforming primer pockets. This did an excellent job on most cases, but like you, I experienced some cases where the pockets were a few thousandths deeper, and the tool would only uniform a portion of the pocket.
After years of doing both (i.e., uniform and not uniform) and shooting thousands of practice rounds on target, I can tell you that it has made no difference that I can detect on target.
The one concern I would have with a uniformer that you can vary the depth of cut is that one might cut it too deep thus creating reliable primer ignition problems. So, take this for whatever it is worth.
Take care and Good Shooting.

Making a difference on target? Who knows. Probably not. I only ever did it to assure proper primer pocket depth to seat primers properly.

I like the K&M, just to clean the bottoms.
Nice 'J'. What's your sound support, pedals?
