The Beretta Optima HP (a-400) super steel choke tubes have been beefed up with Carpenter 455 stainless steel, adding more strength to this choke to withstand steel shot and other heavy Tungsten shot shells ammunition. Due to the thin wall design of the Optima HP choke system, Carlson had to use a tougher material than the 17-4 stainless steel used in other tubes. By using the Carpenter 455 material Carlson has manufactured a choke that hunters can now use with steel, heavy shot, and other Tungsten shot shells without worrying about the choke tube swelling and sticking in the shotgun's barrel. These choke tubes work with all lead shot shells, also. These choke tubes feature a longer parallel section allowing for less Flyers and denser patterns over the targeted area. These choke tubes extend 3/4 inch outside the barrel eliminating barrel damage caused from prolonged use of steel shot. The longer parallel section allows for use of larger steel shot in tighter choke constrictions. These choke tubes have a knurled extension and a matte Blue finish. All steel shot can be used in the close range and mid range choke tubes, do not use steel faster than 1550 FPS or steel shot sizes larger than BB through the long range choke tube.
