There is a great deal of confusion between marjoram and oregano. They are related plants, but are two different species. They also taste similar, although oregano often has a stronger flavor, and both contain high amounts of antioxidants. To make it even more confusing, cretan oregano, O. onites, is also called French or pot marjoram and Greek oregano, O. vulgare, is often called wild marjoram.
Cylinder choke is an unconstricted barrel. The shot pattern spreads quickly. Improved Cylinder choke has a slight constriction. It allows the shot pattern to spread fairly quickly. This is a good choice for quail, rabbits, and other upland game. Modified choke has moderate constriction. The shot stays together longer, making the pattern denser and more useful at longer ranges. This choke is used often for dove hunting and is the preferred choke when using steel shot to hunt for ducks or geese.
In firearms, a choke is a tapered constriction of a shotgun barrel's bore at the muzzle end.Chokes are almost always used with modern hunting and target shotguns, to improve performance. Their purpose is to shape the spread of the shot in order to gain better range and accuracy.n the case of choke tubes, the amount of choke for each barrel is usually stamped on the side of the choke tube, or there may be thin slots cut in the exposed rim of the tube at the barrel opening with the number of slots corresponding to the number of *'s in this table.
