Ok, in my 11/87 I use a Carlson's turkey choke, it is unreal tight at 40 yards with 100% of the pattern in a 20" circle, a tad tighter with 00 and 000 buckshot.
I shoot 3" mag Remington #4 buck on everything, coons are tough and the #4 buck cuts through the briars very well for fox.
Another issue, it has become very difficult to find the Federal 3" copper plated BB's.
I do load my own buckshot and BB's.
Natchez did have sales on Rem 3" #4 buckshot from time to time for $5 for a 5 pack, this stuff is what my Rem 11/87 really likes along with hand loads.
It is difficult to impossible to carry different shells for different animals, and it breaks my heart to spend $3 per shell for the best shells on the market.
Good luck
