I learn't another method of loading some difficult cameras..
First place leader in take-up spool. Advance the roll.
As soon as it holds and also rest on sprocket teeth, drop cassette,
into the recess. The Pentax Spotmatic has very little space for that!
Make sure cassette can move up and down.Not jammed.
Nikons, Nikkormats have more space.
This was taught at a Photo School. It works.
My M3 and M6, I load in dark whenever possible, gaining extra exposures..
