I run 12 Ga 3” TSS #9 with factory full and the pattern is ridiculous @ 50yds.

Strictly my opinion - If I was using a 12 ga - I wouldnt change anything - 3" lead turkey loads. If you can't get a turkey within killing range of 12 ga 3" lead loads, you are turkey hunting for the wrong reasons. I do see an advantage of the TSS style loads for smaller gauges.

Agreed, but one advantage is not having to have quite as tight of choke in 12ga. You probably could use TSS and a Mod choke and be fine in 12Ga.
I like the idea of a little more margin for errors in aiming.
