I just got my first roll of Velvia 50 today. I went to load it into my bulk loader so I could roll some film for this weekend, but it doesn't fit in my loader. I have put 100' rolls in it before, but the center spool on the Velvia is making the roll to big for my loader. I tried to push it out but it feels like the film is attached to it some how so I didn't press my luck with it. Any suggestions? Do I need a new, bigger bulk roller?
