My brother bought a Patternmaster last year and i read about them and decided to get one. I have heard stories about a guy killing a Canada Greater at 55yds with 2 3/4" in BBB and dropped it. My brother went snow goose hunting and hit 3 snows at 50yds and broke both wings and a neck with 3" BBB. Somemore geese flew over above us at 85, 90 yds and he broke a wing on each bird and they fell from the sky, these Patternmasters are amazing. I decided to buy my own and hope to use in for the spring snow goose season here in ND. People that i know that have a Patternmaster use 3" #3shot for geese instead of BBB or BB. The birds that were shot at 50 yds were as dead as they were shot at 20 yds. After results like this I now own a Patternmaster they are wonderful!
