Ammo shopping.

IMHO, and you know what they say about opinions, I wouldn't buy Remington steel shot if it was free. Ha! Ha! I use Winchester and or Federal, I like Drylock but Expert seems to work as well. Like TD said I like the faster loads, I will give up a few pellets for speed, I also agree with fabs on size except for one exception.
If the geese you are shooting are lessers, and or white geese, instead of giants, #2 shot is guite large enough to get the job done. I kill a lot of mallards with #2 and those little geese are not much different in size. HOWEVER, they also tend to not decoy quite so close, so right back to the big stuff. BB's B's and T shot.
Well that's about as clear as mud, guess that's why I carry so many different boxes in my bag. Waterfowlers are like women and makeup, something different for all occasions.

P.S.
An after market choke tube can make a big difference also. I like Briley, my son and friend use an Undertaker. All are better than the factory tubes, again, in my humble opinion.
