As noted earlier, I was able to get some powder from Hodgdon earlier today. I went back to the site to see if I might have overlooked any other available powders and a message appeared, "Only 5 units of any item available per order and only one order per month allowed." They obviously are trying to prevent the Gunbroker vendor types from hogging availability.
Personally, I would rather support my local dealer but when the only choice is buying from the manufacturer, that is where I will buy it. I noticed that you could also place orders directly with Sierra. Problem was, they were sold out of everything.
noticed yesterday: While bidding for an item (firearm) on Gunbroker, I checked out the bid history as the item was coming to an end. Everyone that was bidding against me were new bidders with only 1 or 2 in purchase history. This compared to my 60. New shooters entering the market are screwing things up for us that have been doing this for a lifetime.
