choke tube selection?

Hi Red, I'll try and give you a little input here.1) A 12ga barrel should have a bore diameter of .729" (unless back-bored). Your .683" choke is actually a "turkey choke".Full ~~~ .030 constrictionXFull ~~ .040 constrictionTurkey ~ .045 constrictionI would try patterning again with a more open choke and see how the patterns are. If the choke is TOO tight, the patterns open up. As shot sizes increase(usually around sizes #2-#4), so should the exit diameter of your choke in order to maintain the same pattern.2) For coyotes with Hevi-Shot use Full, XFull or Turkey. Hevi-Shot patterns tighter than lead out of the same choke. Not sure of the exit diameter of the "Dead Coyote" tubes.3) Absolutely! Better patterns and less recoil.
1) ...lead BB's in a 12ga Rem 11-87 Full choke (.683") tube with mixed results...2) ...tight choke tube with Hevi-Shot...3) I'm considering having the forcing cone lengthened and polishished when the barrel is shortened.

I haven't use the shotgun but I know the guys on here that have already commented have made lots of kills with it. Maybe you should go back and reread what they had to say. If I'm not mistaken, they said you won't get reliable 50 yard kills.
... but neither was acceptable for reliable 50 yard kills IMO.

you are correct. I measured it this morning and it is exactly .709"I plan to get out and shoot some patterns again this weekend. Some with a new choke and some with the ones I already have. Will also pick up some Hevi-Shot or Rem HD to try. What do you all think about having the forcing cone lengthened and polished? Do you think that might extend the range a bit or at least improve the pattern? Or is it a waste of money? Any opinions?
A modified choke should have an exit diameter of .709".
