I've used the long Harris with a swivel off and on for several years on a 17 Remington for coyote hunting
. For the first couple of months, it's extremely awkward to use, but once you get used to it, they are great!
I'd pull the legs all of the way out, set the rifle but on the edge of my right jacket pocket and when the coyotes come in, I don't have to raise the rifle, just lower my head.
With practice, it even helps on the 200 yard running coyotes.
