Constriction or choke

[ch]

My first parker was a lifter 12 with every issue you don't want. Bought it because I wanted a gun to shoot black in. New nothing ended up here Thanks for help over the years. So my little boy wants to go goose hunting so I decide to shoot the lifter twist barells. I loaded 81 grains of 2f swiss and 1 1/8 oz of BB nice shot it has .051 constriction do you think a couple of boxes of shells will do any damage? To much to little black? O and a shout out to Craig Smith if you need wads for loading. best ch
