My wife uses 12 ga lightfield lites in her slug gun. And they perform very well out to 125 yards. I tried thm in my gun and they didn't group very well. Probably because I have a 3" chamber and these are 2 3/4". The "jump" to the rifleing is throwing off the accuracy. At least that is what I was told by lightfield. And I have a problem with my slug gun as well. I am a fairly big guy, and my mossberg 695 kicks the snot out of me. I think I am going to get a Remmy 11-87 deer gun next year. My wifes 1100 deer gun shoot slike a dream. But alas, they no longer produce it. Good luck
