Hi, I am an absolute beginner in developing my BW film, I have just started a few weeks ago and so far I have processed 4 rolls (35mm, all 36 frames). Almost all the times, when I load the film into my plastic reel (Paterson), I have jams at the end of the process, so I usually end up doing it over again 2-3 times. I have tought that maybe I am not cutting enough leader away from the film and that the film reach some kind of physical "constrain" when I am about to finish, causing the jam. Before wasting a roll doing a test in the daylight to see what happens, do you think that maybe cutting some more leader would help (with the risk of cutting through the first frame)? Or should I look for other causes? I should add that my Nikon camera forces me to skip the first frames (making blank exposures) before the metering starts to work (usually 3 blank frames).
