Need some quick goose advice

Not a goose hunter at all and seldom hunt ducks. Got invited on a guided hunt this weekend up around Haskell. Supposed to be a lot of birds right now. I was told we'd be hunting fields out of pit blinds and shooting mostly decoying birds. I have two choices of shotguns, a 12 O/U with fixed M/F chokes or an 870 with interchangeable chokes (I have IC/M/F tubes). Both are 3" chambers. The O/U is my go to gun for just about everything, but I'm wondering if I need to break out the 870 for a more open choke and to get a 3rd shot? Also would appreciate advice on a good load for geese? Thanks!

I would take the 870. 3rd shot and the choke seal the deal.

870

3" BBs. I like Kent Faststeel, but any will suit your needs well enough.

Generally it is advised not to shoot steel through a full choke, so going to the 870 with Improved or Modified would be best.

870 with the modified choke. That 3rd shot will come in handy.

I don't think the 3rd shot is all that important (I shoot an O/U for dang near everything so I am biased), but the choke selection is a clincher

I would throw the improved in there and go rock that goose arse.

Take the 870. Depending how nice the pit is, that can be about as dirty of a hunt as you will find. Wouldn't want to take a nice o/u in the pits I hunt.

870, I like shooting #4s for geese. Most guys will say 2s or lower but for my money a fast number 4s kills more birds that are decoying. It only takes one pellet in the head to kill a goose and fast number 4s gives you more of a chance to make that happen. As far as chokes I or M should work for decoying birds.

Good luck have fun, sit as close to the guy calling the shot as you can...

Thanks guys. That's exactly the type of info I'm looking for.

Thanks guys, had a great hunt. We got 1 snow, 4 speckled bellies, 12 Canadas and 5 ducks.
