Shoot it first
I think I would shoot it off the bench a while. It may not need much "tweaking" I bought one when they first came out. It is for hunting. It's a wood stock with iron sights. I have QD rings and a Zeiss 3.5-10 scope. At the time I bought it brass was unavailable. I bought several boxes of Rem. loaded with 180 gr. noslers. Once I got used to the recoil and got it sighted in it shot 3-shot groups at 100 yards that were almost without exception 1 inch or less. My hunting partner bought one at the same time only with comp. stock, stainless steel and had a brake put on. His shot the same. He decided not to reload. I do, but I'm not beating those factory groups by much.
If you don't abuse the rifle, i.e. heat the barrel way up, it's going to take a while to wear it out. Without a break I think you will find this rifle will become less than comfortable to shoot off a bench real fast. I don't like brakes, however I have shot my partners and it's not much worse than a 30-06.
With the exception of trigger work on Remington’s I don't usually mess with factory rifles used for hunting. I did spot for a couple guys the other day that were shooting for groups at 600 yards. One had a 300 RUM the other a 30-378. Both Remington’s and both with fluted 30 and 32 inch SS barrels put together by some Smith in Oregon. I'm not sure what the advantage was to the longer barrels. Someone else on this forum will have to chime in on that.
