It'll work, but I wouldn't use it... I'm betting we're talking a significant size difference (I'm ignorant of PEI's coyote population admittedly) between the coyotes between here and there however. Here they get up to the small end of wolf, like the guy above.
30-60 lbs, biggest on record caught by a trapper is 68lb.
I didn't realize BC had larger coyotes, I understood it was only Ontario and East that had the big fellas. I know the prairie coyotes are smaller but the eastern ones have some wolf dna, unfortunately that also makes their pelts less valuable as they are darker and coarser.
So far all of mine have been shot with a .223 or 22-250 (and one wounded one was finished off with a .22lr at 25 yds, a 22 between the eyes drops them just fine)
What kind of ranges are you shooting them at with the 00buck?
Is "Dead Coyote" still available, if so, seems like a no brainer, heavier than lead designed specifically for coyotes.
Found this on another Forum, I think any of these should be fine at the right range and if legal in your province:
No. BB (.18 caliber)
BBB (.19 caliber)
T (.20 caliber) (Steel shot)
No. 4 Buck (.24 caliber)
