I run a beretta 390. I shot several combos out of it over the years. These are all 40 yards with an pops factor built in.
Comp n choke XX full with, 2 3/4 winchester XX 4s
Kicks GT 660 with Winchester extended range 5s or 6s
Indian creek 665 with Hevi 13 2oz 6s.
These were all great combos for me and killed many birds. Ive probably got 20 dead gobblers with this gun. The last bird was a Kicks win 5 kill
A buddy also has same gun and liked my comp n choke with lead 4s. He has been running that combo for a few years and says he loves it.
