You will spend more money than what its worth.
Not so. With the shot supply I have from a purchase three years ago, I am currently reloading AA quality shells at $2.52/box. However, even buying shot NOW, I will still be reloading AA quality shells for $3.68 a box.
Have you SEEN the cost of AA or STS shells in the store? $6.00+ easily.
Shot is the price burden, so save money elsewhere:
-Claybuster or Duster wads (~$8-10 a bag of 500, $0.016-0.02 each)
-Wolf 209 primers (~$19 per 1000, $0.019 each)
-Scavenge hulls from ranges (I can
routinely scavenge 500+ hulls from the range on a given weekend)
-Shot can still be had online for $39.99 a bag and they ship US Bulk rate postage at $8.50 per
75 pounds.
I use a MEC 9000G to reload about 500 shells and hour when I do a session. Between trap, skeet, sporting clays, snipe, dove, crow and small game, I am saving myself a LOT of money.
