I was looking at the .243 for a dedicated coyote gun, with maybe a little deer hunting on the side. Any dog within 500 yds would be in danger. I love the .223 but I don't have much confidence in it past 300 yds.
I actually thought about buying one and then getting it rebored/rebarreled for the .260, but I could probably pick up a custom barreled gun from a small time maker for what it would cost to buy the rifle and have the work done.
Not many factory choices in .260 with a stouter contoured barrel. Savage has on with a heavier contour, but the barrel is only 20". I'd like a bit more barrel length.
