First started loading shotshells in the early 80's with a $25 Lee loader, and loaded thousands of shells with it. Still own it.
25lb bag of hard shot at that time was in the $20 range. Powder prices, I don"t remember But the prices have increased a lot less than the economy if I remember right.
At the time, I could reload Premium loads for the price of Dove and Quail loads. If I remember right, I got 14 boxes of shells with a pound of powder, and a bag of shot plus primers. Hulls were once fired, and free for me.
Got into Trap, and some skeet. Guy that was local got into it big time, and still is, buys lead shot by the ton to shoot. He did this so the rest of us could get a good buy like the group buys we do on this forum.
There was a supposed lead shortage in the late 80's if I remember right where the prices went so high that shot was at $40 something a bag. Anybody that had a surplus got a bonus.
Currently load with a RCBS Grand Progressive.
I haven't put the pencil to paper to calculate any savings, but casual looking around at prices will support my claim that one can still load premium shells for low cost shell prices.
If one factors in the price of the reloader, you might not break even for awhile, but its all about how much time it takes and how much you shoot..
