BPI has USA TSS for 84$, which unfortunately is the cheapest I have seen lately.
I bought 5lbs last year for 48$lb, should have bought 15lbs and been done with it!
I am down to 2,5lbs of shot, like a dummy I tested a couple new loads and chokes as well as went to a dot sight, so I burned up some rounds the last two years. If I would have left things alone I would still have a good supply.
However in the grand scheme of things it is still worth it to me to shoot TSS, though my thoughts of a season of killing all my birds with dove loads may be in the near future!
Not willing to go back to toting the 12ga!
