What chokes?

[WDFW-SUX]

I think pattern density is the most important thing when it comes to killing things.... the more pellets you put on target the more chances the lights are going to go out quickly.

mod for jumping ponds full for field hunting

With lead, I used full choke a lot, even on decoying birds.......then I could kill them at 20 yards or 50+.  Once we had to use steel shot, I never used full choke anymore.......especially for the larger steel shot loads.  With 3's or smaller you might get by with full choke, but that size shot is too small to shoot at longer ranges where full choke would be needed anyway.  With 1's and 2's you'll find that IC and Mod will likely give you tight enough patterns for killing ducks at 50 yards. 

I never patterned BB's but I bet IC or Mod will give you very tight patterns with BB's too.  That large shot sometimes needs an open choke to keep the shot from getting bounced around trying to exit the choke; sometimes a full choke will give you some weird flyers and holes in your pattern because the shot is getting forced out of the tight choke....  You just need to pattern it to know for sure.

Dont shoot BB's through a full choke

I used a Skeet choke and 7 1/2 early season and switched to Mod and 5's late season when we could use lead.  Now I keep Skeet I or IC in my 20ga and shoot 4's early and 3's later but then I like to have them feet down coming into the decoys or jump shoot them while hunting upland with the same set up.

Dont shoot BB's through a full choke

Don't shoot steel shot period through a flush mounted full choke tube or an older shotgun with a full choke barrel; as you risk a stuck choke tube, barrel bulge or even a split barrel. In general, steel shot shoots one choke tighter out of most flush mounted or fixed choke guns. If you insist on using a full choke, purchase an extended choke tube that is rated O.K. for steel and other hard, non-toxic shot.

Just adding on to what you posted 270Shooter, this comment is directed at others.

I shoot a mid range extended carlson out of my browning for ducks and long range for geese.  Patterns really well.  I bought a patternmaster a couple of seasons ago.  My partners didn't like it too much in the blind.  It was pretty loud.  So I took it back.  Shot well though..
