i have done it on a model shoot, a trip, and the last time using a Friend's Leica M7.
I realized after shooting for an hour, i was way past end..Yup! A former pro did the dumb thing.
The Pentax ME/ME-Super need one to make a fold in leader,then insert.
It will grab the piece like a hungry dog.
Pentax Spotmatic and K-1000, one needs to make sure the,
cartridge, has play, up and down, after loading, or it can jam..
I actually load a lot of my cameras in the dark..
Yesterday i picked up a color roll, developed and scanned.
My 24 exposures had become 28. 26~27 is usual..
When your cheap, these frames count.😀
