That is basically a rimmed version of the .350 Legend, I do believe. Correct me if I'm wrong, but both .350 & .360 use .357-8" bullets, and both cases are 1.8". For comparison, the .357 Maximum's case length is 1.6". Perhaps one could convert the new S&W X-frame in .350 Legend, to also shoot the .360, much like shooting .45ACP in moon clips in a .45 Auto Rim gun.
