Hey guys I need some help, earlier this year I patterned my 12ga 870 with a Rem super full turkey choke and found that the #6 Federal flight control wad shells was doing just what I needed it to do and I eventually took a good tom at 43 yards with it, flop! Now the bad, I cleaned my gun rather well and put it up to rest until fall but my buddy bought a new 870 supermag so I got mine out and we was shooting and comparing blah blah blah, the first time I shot, boom! Awesome just like it should, the next time and every time after that the pattern is blown everywhere! I mean at 20 yards it is all over the place and before at 20 yards it made one fist sized hole. I also noticed that now no matter what shell I run through it, one of the petals on the wad will be completely torn almost ripped off and mangled all to pieces. The choke tube was tight I already checked, I swapped chokes to an IC and shot some 00 buck through it and the same thing is still happening. The bbl is cleaned with a bore snake after each shot there was no obstruction, does anybody have any clue what is going on? Any advice or answers will be greatly appreciated! Thank you.
