At one time, they would not return bulk load cartridges hereabouts or in my home town over 300 miles away, so I doubt if they will today. This makes things more difficult due to the difficulty buying cartridges nowdays.

The shape of the leader is very important in todays cameras due to the autofeed capability so you might cause a bad feed and a jam at the start. It is not important in the process machine as the leader is cut off square and spliced.
