What are you wanting to use the rifle for, targets or critters?
For that 300-400 yard range I would want something like a 53 grain Varmageddon or V-Max. Better velocity than a 55 and both of these have a very good B.C. This would be for critters of course.
For paper punching I would lean towards something a bit heavier but that's just me.
