Hi FISH-ON, Patternmaster has put their tubes through an enormous amount of testing. It has found that ammunition running faster that 1550fps will not perform very well with our choke tube. Patternmaster chokes, with the patented stud ring, are designed to grab the base of the plastic wad in your ammo and hold it for a millisecond while the shot leaves the barrel ahead of the wad. When ammo is running faster than 1550fps, the studs do not get a chance to engage on the plastic wad, therefore, making them useless. Thanks, Michel [ATTACH=CONFIG]1495[/ATTACH]
