I have an 12ga. 870 with a 28" barrel that I use for both HD and trap. The gun came with a modified choke. I was wondering about the different kinds of choke tubes and what is best for different situations?
Any help?
Any help?
Can anyone explain chokes to me.....

Generally, chokes are responsible for how far the shot spreads out. There are Improved Cylinder, Cylinder, Modified, Full, Extra Full, and Turkey Full choke tubes as well as some others. The IC and C tubes are usually used for trap or close range bird hunting. The M tube is usually used for small game and birds at a further distance. The F produces a tight pattern that can be used to shoot small game and turkey. The EF and Turkey tubes produce very tight patterns and allow shotguns to shoot at further distances with a tighter pattern. These two tubes are usally used for turkey hunting. There are also chokes for slugs so that the slugs can be more accurate.

I know chokes do work... but why? Anyone have a good link to an explanation of the physics involved?

There's a coupla theories as to why they work. The point is they do work. Whether they compress the shot column, retard the wad, both or neither is not important.
Longer tapers seem to deform less shot, thus keeping more pellets in the pattern. Oft the longer taper does the same amount of tightening the pattern without as much constriction needed.
Going from most open, the degrees are something like Cylinder, Skeet, Improved Cylinder, Light Modified, Modified, Improved Modified,, Light Full, Full, Extra Full, etc.
In a 12 gauge, the increments to that list run 0, 5,10,15,20,25,30,35,40 Points Of Constriction and so on.
Makers oft have their own ideas of what constriction is best for a given choke. Briley uses 4 POC between tubes.
All one needs is an open choke for shots up to say, 25 yards, something in the middle for shots out to 40 yards, and something tight for the long ones.
The classic IC, Mod and Full sets do work, but IC's a bit tight for skeet and something in between Light Mod and Mod works better for 16 yard trap for many of us.
There's a couple old threads on this in the floaters.
