Per a gentleman on DG's forum today: "Ellet Brothers only has 40 boxes left after others and myself got our orders".

I sent a report to Brenneke USA's manufacturing rep earlier today as well noting that I have been reading of the difficulties others have been having trying to get a hold of the new cartridges and asked if there have been any production issues. I'll provide an update as soon as I hear back from them. Apparently Ellett Brothers has ordered 300 boxes with currently 260 already spoken for. Being Brenneke USA's largest distributor Ellett Brothers had been the first to receive the new product from the factory but there was a miss-labeling (part ID I believe) issue that wasn't going to work with EB's inventory system so the product was returned and re-boxed. It's been a rough introduction of new product for sure.
