My cost for reloading 12 ga last time around was $5.25 for 7/8 oz (skeet); $5.55 for 1 oz (trap and sporting) and $5.85 for 1 1/8 oz (trap and sporting)...all in, with hulls being free. I figure I saved $25.90 on flats of 7/8 oz; $22.90 on flats of 1 oz; and $19.90 on flats of 1 1/8 oz around here. Another way of putting it is I shot 5 boxes more per flat with 7/8 oz; 4 more with 1 oz and 3.4 more with 1 1/8 oz with the same cost, plus my time (moot point that one). Of course, prices fluctuate and cost of cheapie flats is around $70 right now before tax (on the expensive side). The differentials get even better (for me) in comparison to premium rounds like AA or Rem Nitro. Buying cheaper shot from local guys who make shot will lower prices too. I used fairly pricey shot ($38.95/bag + tax) for these calculations. Maybe I can better these prices a bit by using Promo or Claydot rather than Clays, at least I will see about this after the next order comes in. Cheddite primers, which I prefer, aren't that good a bargain pricewise anymore, from what I can see, and local shot makers are raising prices as lead WW become scarcer and the market will bear it. I'm pretty much at the point where I just get the best price I can with factory shot for a variety of reasons. So it goes...
