Need choke.tube and shotshell recommendations

I just bought my new duck gun, a Browning silver 3.5. I've shot some #2 steel through the factory chokes but have holes in patterns at 40 yards. Let me know what chokes and ammo work for ducks in your gun. I think I'm good for decoy range but need a 40+ yard choke tube and steel shotshell combo. Thanks.

I shoot Improved Cylinder with 2\'s, 3\'s, and 4\'s in a Browning Gold 3.5\' the gun does well with this set up, best advise is to play with your gun and pattern it so you know just what it\'s doing at your desired yardage, as far as ammo I look for Max Drams Powder and Max Shot Weight. Hope it helps

Patternmaster Black Cloud. Or any of their other extended long range chokes. A little expensive but they are so worth the added cost.

Teal Season: #4 waterfowl loads, OR #6 STEEL dove loads (cheap!) via Carlson extended Skeet choke. This year will also dabble in 20 gauge during teal season.

Regular season: 2's (field), 3's (marsh) via Carlson extended Light Mod for most of season, Mod or Improved Mod for late season.

Seeing some new loads with blended shot sizes being offered for Fall 2019

I have a Silver and an A-5, both do well with improved modified choke and #4 steel for ducks or #2 steel for a duck/goose combo load, 3 1/2”
I also have a Carlson waterfowl set and the trio works real good basing range to the choke
If you don’t mind a little extra cost heavy shot or Rio bismuth are both awesome, I use both as I like the drop um dead these do as I use a retriever and swimming cripples is rough on a dog

I shoot all ducks (teal, greys, mallards) with 3” 1-1/4 oz #2 steel shot at ~1400 fps (depending on brand) out of a modified choke in the marsh, it works great for me for decoy range out to 40-50 yds.
