FYI, new shooters: the R-1100 Trap model's barrel has a small stud in the tang that has the same function. I still use a shell catcher 'cause I want my hulls for reloading.Dave McC said:Besides the bands, some folks with 1100s and similar have two small holes drilled into the barrel extension and a small horseshoe shaped wire inserted. It directs the hulls more or less down, thus solving the problem without impeding function.
Another way to annoy other shooters is to delay the club's progress by harvesting your grounded hulls between rounds. The practice is prohibited at some clubs.
