Hi folks, not much out there on reduced slug loads in shotguns. I was wondering if anyone has any data or or links on this subject. I'd like to load down below subsonic level in 20ga with some slugs for fun. I dont mind working all the way down to mousefart levels in pistol cartridges. Shotguns though are a different kettle of fish, would rather find some sources of information . If anyone has loaded slugs at low speed would be interested to hear.
