I was shopping over at freestyle and was about to order a 100ft roll. I've done some figuring this evening, and aside from bulk loading expired 100ft rolls of color film, bulk loading really isn't worth the extra effort it seems.
If you get 18 rolls of 36exp from a 100ft bulk roll, I've figured this...
-by bulk loading TriX, I'm saving $1.32 per roll, or about $24 per 18 rolls shot.
-by bulk loading HP5+, I'm saving $1.78 per roll, or about $32 per 18 rolls.
I can't find much in the way of color film in 100ft rolls anywhere, so aside from expired stuff at Ultrafine, there isn't much figuring to do because those last remaining expensive single rolls are the only thing out there.
So if realistically I'm only going to be bulk loading B&W film, and it takes that much longer to do, is my time really worth the $24-$32 extra savings?
The only advantage I can see at this point is the fact that bulk loading will allow me to roll 12 or 24exp rolls. Which in the long run is actually going to cost me more per frame, because of the amount of waste from leaders etc...
ETA: it looks like B&H has 100ft rolls of HP5 at $49, which works out to a savings of $2 per roll, or about $39 per 18 rolls. Which is a little better than the above.
