Several new Hornady shotgun slug loads have been announced at the 2013 NASGW Expo: two Superformance shotgun slugs and an SST Lite Shotgun Slug.
The new Superformance slugs will be available in both 12 gauge and 20 gauge. Both loads use a MonoFlex slug. Originally developed for lever guns, the MonoFlex design uses a monolithic hollowpoint bullet with the famous Hornady Flex Tip. The slugs are made from a gilding metal, instead of pure copper, to increase their strength and retain 95% of original weight. This helps the slugs to penetrate deeply.
