The Heavy Magnum coyote BB is actually designed for modified chokes.
If I really want to go long then I use a 3.5" shell with 00 and a stock full choke. I'd feel good at 70.
But I really like how #4 patterns at 40-50 yards. In Washington woods it is pretty ideal.
Nicest coyote I have ever seen was at a waterfowl spot. Walked out some with binocs and it was about 10 yards from me :'(
Just be careful since some of those waterfowl areas can have some really nosey neighbors. I've had someone call because they thought I was going for deer in spring
