Thread: 20 GA for ducks

i had some bismuth last year i got given. was brilliant but smashed the birds to pieces. Was loading 36 gram 6s as thats the load data i could find. i did buy some falcon stuff too for a good price so i could open them up and scab the shot for the 410 but it think 4s are a bit big. Id like at least a 7 shot or smaller.
