My 12ga is a Benelli Nova. I used a Carlson's flush-mount Extra-Full (.685) and it worked very well. Two years ago it was from about 15 yards. Last year, it was 42 yards...both good solid kills. Those were using the old ones without TSS or the new Flex wad. I've shot the new ones this year and they seemed to pattern the same.
My 20ga. is a Remington 870 with Carlson's Extended Turkey Choke in .575. It's a new gun this year so haven't had it out in the field yet. I thought it patterned to my expectations from 20 and 40 yards but didn't take any pictures. This is the current 3rd Degree with TSS and flex wad.
