Something like a 145gr eldx getting over 2900 out of a shorter barrel with superformance powder. The general consensus was a magnum suppressor with 18" and no shorter than that.
I have a .308 and if I punch those numbers into the ballistics app makes the short barrel .308 looks like it has the trajectory of a brick.
The recoil will still be a lot less than any magnum and very manageable.
Put it this way, if guys off this forum can shoot deer with a .270 and lrab out to 800 odd yards going 2800ish with adi powder in a longer barrel. Then out of an 18" or 19" barrel with more modern powder going the same velocity you have a pretty versatile setup.
Worried about recoil, just download some 120gr or 130gr ssts or nosler ballistic tips for closer stuff.
