Wondering, does any one have a component analysis of a Gun Club vs a STS shell. What is the primer difference? What is the Powder difference? What is the shot difference? It would be great if a cost analysis could be found. I'm guessing its less than a buck a box. If Walmart can sell them for $7.57 a box the cost has to be less than $5.00 including transportation. Two years ago you could get STS for about $50.00 & Gun clubs for $32,00. The price of all the components except primers has fallen & wads & powder have remained fairly constant.
