I've got a fair chunk of 4x5 in the freezer, but most of that is out of date odds and sods that I have got cheaply, rather than deliberate hoarding. I have, however, got 100 110 cartridges due to be reloaded with 16mm tri-x and plus-x. Twenty would have been enough to get over the inevitable failures when cracking them open to reload but the price for 100 was so cheap that I did the big purchase. The supply seems to have dried up now so I probably did the right thing but it still seems to be way too many.
