We found at certain ranges they did not pattern well and would blow holes in your pattern.

For instance they where okay 10 to 15 yards and then 25 to 30 yards but we had a heck of a time at 15 to 25 yards.

In fact my partner got so mad because he missed a Tom and should not have that the box now is in the bog bottom and I am sure they are still there and are free!
