I’m having a problem loading my film. When I load the feed side of the mag and run the film through the take up side, I plug the mag into the camera and do a test run but there’s a bad sound and the film gets spooled up in the feed opening, there’s too much slack that doesn’t go away when winding, and the stock gets punctured. Is there any way to fix this? I changed to a different mag and it’s still a problem.
