First off the .270 is fine because while the bullets are .277 the regulation specifies the bore of the rifle which is measured land to land and is less than .275.
If you are hunting coyotes avoid the rimfires. The .17HMR or .22 aren't enough to reliably take them down.
I live in a rural area of Southern Ontario and am within the region requiring the .275 limitation. I use a 12 gauge shotgun, .223 and a .270. I'd be just as happy with any caliber in between those two. I'd also consider a .22 Hornet if ranges were no further than 200 yards.
I've owned a 6PPC and it's an outstanding cartridge but one that requires reloading. As noted above the .243 would be a better choice. If I didn't have the .223 and .270 already I'd have a .243.
