All,
I just shot these yesterday to try to get my scope sighted.

As BigCountry mentioned, they sure do leave a lot of lead in the barrel. I had to clean it 3 times!
I put 15 slugs in a 12 inch group at 100 yards. I think I stated getting sore and began to wander. I think I'll had more success with Sabots and an easier cleaning job. I learned a lot.
