Bearhunter, was that half a ton for personal use or a business? If the former, you must have gotten enough for a lifetime of reloading!!
No, it wasn't for business but I did purchase large quantities, when they became available for a few different stores to put on sale as customer draw items.
Back in those days, hand loading was akin to alchemy and 80% of people honestly believed all hand loads were ticking time bombs, waiting for some fool to pull the trigger and blow off their hands and destroy their firearm.
In some cases, they may have been right. Many people back in the day had no idea about powder burn rates etc. and there were some spectacular Kabooms.
I often had 50-100 pounds of powder on hand and sold it to acquaintances at 25% over all of the costs of getting it back home.
Bruce Hodgon was very hands on and approachable back in those days and Alan Lever introduced me to him. Alan bought a lot of powder from Hogdon's and most of it was sold to other businesses as bulk lots, after being repackaged by folks like Tom Higginson, who was a personal friend of Bruce Hogdon.
I never made a lot of money from those large purchases, simply because they were pretty much available to anyone that was willing to drive to Kansas and pick it up in large quantities.
Never a bit of trouble at the border crossings. Many of the officers were hand loaders and shooters who were quite interested in what was going on. Of course, they frowned on folks that didn't declare what they brought in.
The main reason I did this was it paid for decent vacations and I could usually shoot for free with the proceeds.
There were some deals that were quite lucrative, but usually they included surplus ammunition, both commercial and military and often firearms.
Those days are long past now, but I learned a lot and got to meet some extremely interesting people along the way. Some, such as PO Ackley/Tom Higginson/Alan Lever became personal friends and kept in touch right up to their time of passing.
I miss those heady days and many of those people.
