I tried them about 20 years ago on ground hog with so-so results. In a 6mm rem savage 77 varminter and an H&R ultra. The molds were harder to get quality bullets from then fatter slugs. I only tried about 150 of them and went back to the jacketed bullets. It was easier to get great accuracy with jacketed than cast. I was into heavy .30 cal cast and that took most of my time.
