I haven't shot Triple 7 in the Wolf, but it does shoot fine with 80-90gr of real FFg BP behind most sabots. I just love the B209 for easy cleanup. Breech plug cleaning after BP sucks.
BH209 is much easier to clean, but the crazy prices and lack availability has pushed me back to loose 777.
Yeah, if I was just starting in BP now 209 probably wouldn't be my first choice. I bought a few cans once I found out my Wolf liked it, shortly before prices went bananas. I pretty much only shoot it to check my zero and then hunting, so they'll likely last me most of, if not my entire life.
I'd probably go BP or Pyrodex if I was starting from scratch now. I used to shoot 777 in a Traditions percussion 50 cal, but I always had problems with it getting full of clumps.
