I'm new to shotgun reloading and I'm starting up with the Lee 1oz Key Drive slug. On the Lee load data they show
Win AA hull, W209 primer, WAA 12 wad with 36gr of Herco for 1587fps.
For the most part I do not need that much velocity as this will not be used for hunting. I'd like to bring the velocity down to around 1100-1250.
Any suggestions or safety tips on reducing the charge?
