Agree somewhat. I'm normally on the same page with BEN but not this time. There is nothing delivers like a 10ga even with steel shot.I have been reloading all my own steel since a year after it 1st became law and with my duplex reloads around 1700 and the right choke I kill almost like I did with lead.
In fact this year for the 1st time I started using the 12ga 3 1/2 again for just duck hunting since the 10 was just tearing them apart over decoys.
No 12 ga 3 1/2 will ever pattern as nice as a 10ga.
I have two browning gold, a BPS and a rem sp-10 in 10ga and two 3 1/2 browning gold 12ga 3 1/2, plus my maxus,etc and have done a ton of testing since the mid 90's with different chokes , guns and both factory and RSI reloads. The 10ga gold with a briley IM diana choke will kill 65 -70 yards if I want to try no problem and has when I hunted snow geese out west.
Like I said it can be real hard on ducks under 35 yards if you can hit them. Ammo unless you reload is more expensive and hard to find at least down this way.
Some reading from BP. Try a 10ga once like they say and I know you will buy one if you are a goose hunter and don't mind the weight and shooting last in the blind

I agree with twotone and 3macs1. I shoot an SP-10 a big percentage of waterfowl season. The 10 gauge is amazing. When my two boys hunt with me, they always want to shoot the 10 gauge.
