yes I did. was very tight...in my opinion too tight for a youngster and unnecessary at 25-30 yds and even a little further. I want some room for error when the kid gets excited, jerks the trigger, shoots at a moving turkey, etc. all things that can happen. With the superfull at 25 yds it seemed like every pellet was in a 10 in circle. May not have been that bad, but was bad enough. I didnt shoot it at 40 yards with the modified. Every gun can be different so give yours a try. Id bet yours with a modified will be good to go at 30 yds or less too...good luck. Oh yeah, I did deep clean the barrel as per instructions on this site also
