I invest 6-8 hours of scouting every week, plus setup, and take down time, for our weekly goose hunt, and if I had to shoot 40 yards plus just to shoot a box of ammunition per year, I simply wouldn't bother hunting geese. Yes you will kill some geese at 50-70 yards, but you likely cripple as many as you recover shooting that far, to me, shooting that far, with such limited shot opportunity isn't worth the effort to me.
It is all what you are familiar with. If it is all you have you get good at it since we don't have many hunting options down here
My old buds went about 8 times this year and got 6 geese between them did lose one but not from too long a shot from the tide taking the dead bird out to sea on them
Cheers
