SavageT, I have used them. I have about 50 rds left out of 1000 rds I ordered about 2 years ago. They shot fine and with good accuracy out of my 3 shotguns. They work well on light to medium game. For heavier game the Brenneke's are the only way to go. IME the Brenneke's will give you about 40-50% deeper penetration than any other brands. I don't know what your hunting, so you may not need the penetration. In a smooth bore barrel I only use the foster type slugs. Hope this helps, Byron
