I haven't used their loads specifically, but many other reloaded shells. Most days, it was never an issue, but a dud that left a wad hung up on my patternmaster and stuck out like a fully bloomed daisy changed me.
At 1350 fps, T shot is doing over 600 fps over 60 yards. That's enough energy retention to still penetrate vitals on any goose. To me, the speed over 600 fps is wasted when you could probably sacrifice 300 fps from that fast load and add a 1/4 oz more shot to the pattern. I'm a fan of density over speed. I use 1 3/4 oz Federal #3's for ducks. My pattern is denser 10 yards past my chokes designation that a 11/8th is 5 yards in front of a 12 ga's optimal distance. My mod choked gun is denser at full choked range than a than a 12 is on the money. To me pellet strikes have proven more effective than penetration and pass through.
Just personal opinion.
