They dropped the 15g/cm Heavyweight in favor of the TSS loads, which is smart on their part.
They have announced a bunch of new TSS loads for this winter/spring.
Kent and Browning have also announced TSS loads.
Great on more people making TSS loads because it should drop price as supply comes up.
I've been using 13 g/cc hevi-shot with good luck for years and the 15 g/cc heavy weight 7-shot should help my pattern.
Still having a hard time believing TSS 9 shot will penetrate like lead 5 shot, but I'll trust the more experienced turkey hunters here on that one.
