I'm going to go out on a limb and say that my Gamo Urban really likes these H&N Hornets. I bought some to give a try for squirrel hunting. Once I sighted the scope in to the new pellet (I have been hunting with the JSB 18.1) I stacked 5 in the same hole right at the bullseye at 30 yds. Just to make sure, I put up a new target and got this with the next five. If you have an Urban, they are worth looking at for hunting.
