Tri-X 400 + Rodinal: How to get big grains with normal contrast?

[fixbones]

Any pointers?

I have tried 1:25, 1:50, 1:75 and also developing with higher temps 22, 24, 26, 30 degrees. Got some grain but still not satisfied...............

If you scan, it is enough that you use some sharpening, the grain will pop out right away ( provided your scanner has a resolution good enough to resolve the grain - the flatbed Epsons do not). Otherwise, your best bet would be using higher speed film.

If you print, try to get low contrast negatives (overexpose + underdevelope)
to print with grade 4 o 5. You will see then the grain.
