Turkey Choke for 4 buckshot

[prairiedog555]

Hello,
I shoot coyotes, usually using various rifles from .22mag to 30.06.  But in certain times of the year like early fall they tend to come in close. 
I have an "ultra tight" 12ga. 3" turkey choke that I use #5's with and I wondered if using #4 buck in it would be good.  I think most shots will be 40 to 60 yds.
Or, since I am not an expert on using Buck Shot would another standard choke like Full or Mod be better? 
Please advise on use of OO buck also.

Thank You

Carlson makes a coyote choke.
Tight like a turkey choke, but ported.
Claims to be good for buckshot out to 70 yards.
Bought one, but haven't used it yet.
Don't know if its for real,  or just marketing, like the quail urine I put on my boots to go quail hunting.

all guns are different
you will  have to shoot yours and  see


i have  heard  modified  is best for OO buck.......but  also  heard  full is better


i  know  my full choke  loves OOO


but  #4  seems big enough....so go for the number of hits


try different sizes  and brands

All you can do is pattern your gun with what you have now using #4 buck and then try the longer choke if what you have is not adequate. #4 buck is probably the best all around size easily and affordably attained. You need penetration and BBs are a bit small unless really close. I've read that aerial gunners for coyotes use mostly #4 buck in 3" mag 12 guage.
