I've not had a lot of experience shooting Coyotes with the shotgun, maybe 7/8 total,but I have patterned my 2 oz. 10 ga. loads at 80 yards and likely wouldn't say they were.deadly past that. Mind you that's including late arriving pellets that wouldn't have struck the animal if he were moving. These are 4 buck with buffer and a full shot up encasing the.entire column running at.1280 through my chronograph. This is a.very high pressure load using 40 gr. Blue Dot and a federal 209 primer. Wouldn't try it.in grandpa's 10 ga. double.I
The few coyotes I have taken within 50 yards have been clean kills with no chasing and follow ups. Not chastising anyone but if you're shooting at 80-100 yards you are.without doubt wounding.as.many as you.are killing and if.you are ok with that that's up to you.
I have had conversations with top ballistics people who have shot far more birds and patterns with large shot than I and to a man they recommend improved modified .025 construction for large pellets steel or lead.
Just my experience for what it's worth. I prefer a rifle.with its hydrostatic shock for taking coyotes whenever possible. I feel. I owe it to them not to inflict unnecessary pain.
