SDblackhills;
Good afternoon, I trust the first week of June treated you acceptably and you're well.
For coyote calling, we started out back in the ancient days - when nobody believed we could actually call coyotes - in the late '80's.
Buddy was running a Leupold Vari? 2.5-10 on a B78 in .25-06 and I know he never, ever moved it off 10X. The closest I saw him shoot coyotes with it was about 20yds give or take.
I started with a straight 6 on my main hunting rifle calling coyotes, then in the early '90's when I put together a specialized coyote rifle - .22-.250AI - it had a 4-12 El Paso Weaver on it - jammed on12.
With that I shot a few at under 50yds but I do recall hitting some sagebrush in front of a coyote once close in - would less power have helped me see it? I can't really say for sure.
That rifle runs an old very clear 3-9 Leupold now - and yes it's jammed on 9 power.
The other coyote calling rifle I've been fooling with is a Ruger American in .223 and it's running a 10x40 Bushnell - I want to say it was called a 3200 then? Sorry I'd have to go drag it out of the safe to be sure.
They're reasonably priced used up here across the medicine line, usually going for $200 -$250 CDN. It's not super clear out to the very edge, but to me it's been reliable as far as not losing zero. I don't feel it was a bad scope for the money.
When I got it, I was going to give dialing a try, but honestly haven't got around to it as yet. It's got dots too and so far shooting rocks I've just used them.
While we are able to import some SWFA scopes up here, I've personally not looked through one, but my friend from across the Rockies - Jordan Smith - spoke favorably of the ones he'd tried and he does much more long range shooting than I do for sure.
Hopefully that's useful to you or someone out there.
Good luck whichever way you decide and all the best.
