New Daystate Howler Slugs!

I just tried these in12.6 grain - .177 in my Benjamin Akela. Sighting in my scope in my back yard at 10 yards, these are one-hole slugs. I was very impressed with how smooth these cycled through the action. I bought the Akela more for pesting and hunting, and these slugs appear to be just what the doctor ordered. So far shoots pellets just as well. I am going to try to find a similar weight pellet, where both will shoot in the same hole.
