RE: #6 shot
all I have ever used is Winchester #6 turkey loads.tried most all the other brands while patterning the gun and the Win. patterened best in my BPS 3".
I have taken several birds over the years at 50 yards.that is streching the barrel a little,so best to try and get them closer.as with the one's I did take they were at like a last day of the season hunts.
thats what it's all about ; "get them close".
for your question; yes it will take them if you gun patterens "GOOD" at that yardage.
