My new slug barrel arrived via FEDEX today. Like my hero, Bob K, I bought a Hastings for my 12 gauge 11-87. Tried four different sabot slugs (all 2 3/4 inch) this afternoon. The results at 100 yards (5 shots each):
-Lightfield Hybred EXP: 4 inch group.
-Federal Classic Hydra-Shok HP: 2 1/2 inch group, 2 fliers (although, they were touching, so maybe it was a < 1" group w 3 fliers!).
-Federal Premium Barnes Expander: 3 inch group, 1 flier.
-Winchester Supreme: 2 1/2 inch group, 1 flier.
Fliers were within 5 inches. They might have been caused by the barrel heating up (I got a little enthusiastic). The Winchesters nearly dislocated my shoulder.
Anyone have any slugs to suggest?
