Well its your rifle do with it what you want. I personally would not go shorter than 24 inches. I like a little longer barrel, I always have. It will be loud, and the muzzle blast will get you attention at first and last light. And depending on who you talk to, you end up with a very loud more recoil and more muzzle jump and blast at a performance level of a 270 with a 22 inch barrel. You are going to just end up with a loud 280. I would be interested in how it works for you if you cut that barrel down.
