Hi Everyone. So it came down to this: Either I try the bulk loading thing or I simply shoot less. I didn't think I'd be very successful with the former so I chose the latter. I purchased the bulk loader and will start purchasing the 100 ft rolls once all my regular film is gone. Now I mentioned this to a friend of mine who shot lots of film back in the day and he asked me what cameras I was using. I told him Nikon F3's. He said he had a bunch of re-loadable cartridges made by Nikon for their cameras and I could have them if he can locate them in storage. He said that he used to use them with his Nikon F but he seemed to recall that when he began using an F2 they didn't work. So is anyone here familiar with these items? Can they be used with an F3? It would seem to me they would, the film transport in 35 cameras all look the same and they are made to accommodate the same size cassette across manufactures. By the way, are these anything like the Kodak Snap Caps? Another photographer friend of mine suggested I try to find these as they are better quality and less likely for the top to pop off unexpectedly then the cassettes commonly available today for bulk loading. I looked into these Snap Caps and they seem to be pretty rare although I guess they appear on eBay from time to time.
I've used OEM reloadable cassettes for Nikon F and Leica, and they are far better than reusing those cassettes from film companies or other sources which can be reused. OEM cassettes may not work well with some film reloaders. They are expensive, but should last a lifetime. I usually reloaded 100 feet of film into film maker's cassettes at one time, which would have required a big investment in OEM cassettes.
They were GREAT. Much better than any of the snap caps.
I "think" they were primarily for the motor drive, where opening the gate on the cassette reduced the film friction, thus less drag on the motor.
Unfortunately, it appears that Nikon gave up on the Nikon cassettes after the F2. Likely not enough sales to justify making it.
I was bit by the compatibility problem. I have a few F cassettes, but no F, only an F2
For your F3, it appears that you have to use the generic reloadable cassettes.
