As far as reloading I do not think TSS is drastically more money than HEVI shot. Weird thing is they were showing HEVi in 7.5, I have only ever seen it in 7 in the past.
Simple enough to load TSS in 12ga with 1 5/8th oz to save some shot/money, but guys gotta be all they can be most times!
I completely agree on TSS being over kill in 12ga with a heavy pay load, a 1 5/8th oz in 12ga would be a really nice low recoil load, I am actually considering a 1 1/4oz for my 20ga.
