I am taking a defensive shotgun class this weekend. Yesterday we patterned our guns and a few people had Wolf. The instructor said that Wolf seems to be loaded hotter than most other buckshot (based on felt recoil) and it usually shoots a looser pattern although he has seen a gun or two where it shot really good.
So, based on that experience, it probably won't be the best possible load, but it would certainly be good practice ammo depending on the price. I have no idea what it costs. If it is anything like their rifle ammo and you can save almost 50%, I would buy it.
