Ok, so now I've shot and developed 3 rolls of Tri-X in HC-110. The results are ok, but I they do spark some followup questions.
The process:
My bathroom was about 23-24°C but the chemicals were about 21°C. I developed in HC-110 dilution H for 9 minutes. Agitating for 5 seconds every 30 seconds (Kodak method). Then Ilford stop bath for 30 seconds, constantly agitating followed by Ilford fixer for 3,5 minutes, agitating 5 seconds every 30 seconds, like the HC-110. Washing 3 times with 5, 10 and 20 'agitations' (Ilford method?) and finally a rinse with 'battery/ironing' water and Photo-flo. (Battery water is the best I could find, results seem fine). Hang to dry over night.
The results
I've made my own light table solution for scanning the negatives with my Sony A7 and Tamron 90/2.8 macro. Seems to work fine.
But the resulting images have a very compressed histogram, very low contrast, and I presume thats because of some fault in my developing process. Most of them are fixable in Lightroom, but they need to be pushed to the max and this increases the visibility of the noise, which looks awesome, but might not always be welcome. I even need to take some images into Nik Silver Effex Pro and give them the 'Tri-X 400' look to get there haha.
Some samples:
Very narrow histogram and low contrast
Here I've about maxed out everything to get some contrast in the image.
Any ideas as to why my images are so low in contrast?

I've also discovered something that I guess is a problem with the camera where some part of the shutter can't keep up with high shutter speeds (I think only the highest, 1/1000, currently testing). This ruined quite a few shots since I like to shoot with a wide aperture. Any ideas about this? The MX shows the current chosen shutter speed on a dial in the viewfinder, but mine shows one speed faster then the dial on top of the camera. I don't suppose that is related, but who knows...

I've also learned to expose for the shadows more.... Many underexposed shots

Some more samples (These highly compressed by PentaxForums samples don't really do the images justice...)
Thanks!
