Winging bullets at Coyotes is a lot different than being able to make a clean shot on a big game animal. If 9x works for you at 1000yds, then that's great. I would still recommend more scope....just my opinion. Take it for what it's worth...
I've made a habit of smacking deer sized game out past 500yds without anymore than 8x. I've also found no issue messing up a 10" gong at 550yds with a straight 4x easy as eating pie.
I've used a 14x to make sub MOA groups at 900m. That's all clean on game accuracy.
Steady with 4 is the same steady with 24.
