One of the more interesting developments for changing the pattern of a shotgun can be seen here on Leroy Thompson’s Ithaca Model 37 Riot Gun. Most of these, such as switching to a Modified choke, are rather mundane, but there are a few which will grab your attention. While Improved Cylinder is the most common choke used with short-barrel shotguns firing buckshot, there are other options.



Traditionally, short barrel shotguns intended for use with buckshot and slugs by military and LE, along with guns intended for personal protection, have typically been fitted with Improved Cylinder. What is the best choke for a shotgun? There really isn’t one, as the optimum choke constriction will vary with the type/size of shot and distance you will be using it.
