I can only tell you about two I have owned and have tried.I have an older Ithaca Model
37 deerslayer 26in slug barrel 12Ga which I got from my father and wouldn't trade it for anything for the way it shoots.I also have a mossberg 12ga 835a with screw in chokes.I use an improved cyl choke and 2 3/4 in. slugs with good results out to 75 to 100 yds.I have heard alot of people on here who like the rem. 870 12ga but I personally have not tried it.
