My problem is most the film I used to load is no longer available, let alone in bulk. These days I mostly roll BW ( Delta 400 and FP4+ ).
besides the B&W, I have 2 cans of Provia 100F plus what ever is left in a loader, and some old Optima 400 in a loader.
Back when, I used to buy bulk E200. When it went away, I moved on to something else. Now all gone. I get the new E100 once in a while in 36 exposure rolls.
Anyway, I have always found rolling my own to be advantageous cost wise. And, you could probably do just fine without a loader. I find the cartridge gets a bit tight much past 36 exposures + lead in, lead out.
