I've been bulk loading HP5+ and shooting it at 800 for several years. Haven't had much in the way of scratches, and never had a canister open up when I didn't want it to. I use Kodak Snap Caps, and blow them out with air before each loading. I tend to put a bulk roll in the Watson loader and load up all 17 (I think it is) 36 exposure rolls at once, putting them in Ilford green top plastic canisters that I've saved from commercially purchased rolls. I mark the caps of the reloaded film canisters with an "R" (using a Sharpie) to easily identify reloads. I've found that they work fine in all of my manual wind cameras and motorized Nikons, but sometimes the little point and shoots don't have enough muscle to wind a particular cassette. I keep some commercial rolls around for those cameras.(posted 8295 days ago)For processing I've used Ilfotec HC at 1:31 with good results, using the Ilford recommended times for starters and adjusting a bit from there. It's an easy to mix concentrate (like HC-110, I'm told) and the stock solution seems to keep well. Results of my kids' participation in theater productions and indoor horse shows are just fine at 800. I've tried a lot of other film/developer combinations in side by side tests, and haven't found any that were materially better for these purposes (for me and my equipment and my technique - your mileage may vary.)
