If you know what you are doing you can make more accurate and consistent skeet/ trap loads which equates into a savings over top end commercial loads.
Steel duck and goose loads however are never good performers when compared to factory. The fastest 3" loads I can produce with steel are 1790fps but only deliver a payload of 1oz where as Remington hyper steel toss a 1-1/2oz at 1700fps
To level the field a 1-1/4oz 3" steel load travels at 1260-1375 fps reloaded but 1700fps from remington hyper steel, 1695 fps from a Winchester blind side HV, 1555fps from Kent etc
Factor in that each shell has 30+gr of powder, a 209 primer one B.P. Ranger plus wad,22gr of B.P.#47 buffer, one .030" over shot card wad on top of your expensive steel shot and now the time,labour and cost make it economically unfeasible....to add insult to injury reloaded rounds are not waterproof.
Now slugs and buck shot have savings to them if you can get wheel weights etc for casting.
I got my mec600 with 2 bars and a variable shot/powder bar and auto primer for $40 at a gun show so I can't complain on the set up expense.
Bags of shot came from the same show for $12ea so again I m ok for now.
After my old lee melting pot burned out its heating coil I've been contemplating on building a shot dropper from the remainder plus a stove top element.
