I can't help but comment that I think you don't have enough developer concentrate in the drum. Exhausted developer does not process evenly.

I have been using the 8x10 print drum for a number of years with no problems I use HC110 1:50 with HP5 and D761:1 with FP4 .I do how ever use 500ccs of developer, the same amount I use in conventional reel tanks.. The times are quite close to those for roll film .
8X10. Process negs one at a time, developer in 16X20 tray, 2 liters of solution. Stop, fix, and wash trays are food storage containers from Wally World.
Developers are scratch mixed from dry chems at tray dilution and used one shot, right away. Moving to an oversized developer tray eliminated problems with uneven development.
Use the top of a chest freezer in the cellar for a work surface.
Happiness is a load of bulk chemicals, a handful of recipes, a brick of film and a box of paper. - desertrat
4x5: in a Jobo 3006 drum (with 400ml of chemistry)
8x10: one sheet at a time in a Large print drum (Unicolor? or Ciba chrome? )
When it comes to sheet film, I only use Kodak Tri-X (320TXP). I have standardized on a home-brew variation of D-76 which I use diluted 1+1. Both drums are turned by a Unicolor Uniroller model 352. I removed the little plastic thingy that makes it reverse directions so that now, it just goes round and round in one direction.
The print drum gives me fits because it leaks...I've been looking for a better way - shorrt of spending a small fortune on a Jobo 3005.
For everything from 2 1/4 x 3 1/4 to 11x14, I use D-76 or D-76 1+1 in Expert drums on Jobo CPA-2. At this point, film is almost always HP5 Plus.

I use hangers for my 4x5 and reels in Paterson tanks for anything smaller. The soup of choice is PyroCat-HD, semi-stand. For the 4x5 I do not develop any more than 6 sheets at a time. The tanks provide a very cozy fit and hold 1.3Ltrs of fluid. I found if I put in anything over 6 hangers I would get surge marks.
4x5 film, usually tmax
Kodak hangers and Kodak hard rubber open tanks. Replenished D23. Up to 8 at a time.

f/22 and be there.
All sheet film in trays, six sheets at a time maximum.
Tri-X 4x5 in PMK because I landed on good processing times for it and it consistently gives me good negatives.
FP4+ 4x5, 5x7, 6.5x8.5 in Pyrocat-HD. Still working the kinks out but I'm getting some really good results.
8x10 developed in trays.
One sheet per tray (I have a lot of small trays)

As my wife says about the medical insurance business, “Ask ten people, get twelve different answers.”
Size 8x10 and 7x17, Film HP5, chemicals and equipment Bostick & Sullivan’s Rollo Pyro in a Jobo CPP2, Expert drum for the 8x10, 2500-2800 series drums for 7x17. 68 degrees, five minutes development plus roughly another 40 seconds of pour in and out.

I have been doing it this way about five years now.
