Thread: The x55 and barrel length

I've got a nice (to me) t3 x55. Id like to take it out more and I think the reason Ill usually grab something else is because its not suppressed, its fully std. I hand load and a max shot for me would be 300/350m on an animal. I hear this cal likes a long barrel for best performance but it would be too long to thread and put a suppressor on without trimming it back a bit. So whats a good length to trim one of these back to?
