There's a company called rogers sporting goods that has some federal heavy weight 7s left and I am trying in my 12 gauge.
Google them.
Passing it on to people who may want some since it looks like federal stopped making them.
Rogers had federal 20 ga TSS 9 shot too and I ordered some of those based on several people recommending them.
Im forced to use non-lead shells because I hunt federal land so I hope these work for me because they were spendy.
