What to do with my impulse buy….

Before you do anything, examine why the 6.5x284 got its bad rep and what you might want to do with your gun. It was the hot ticket for a while in LR and F class etc. Rapid fire was eating barrels . But for a LR hunting rig, it has basically the same internal capacity as the 6.5 PRC. And hunting rigs don't eat barrels. And in the long action, you can load lots of stuff to whatever you want. Assuming the throat is decently long.

I would do NOTHING until I secured some 6.5x284 brass and tried it. A lot of Savage barrels are shooters. Better put 100 rounds down the barrel to break it in. It won't shoot right away, probably.

I have 200 rds Lapua brass 6.5x284 for my Savage 6.5x284 Proof carbon fiber gun. Sorry, you cannot have them. I did not know that Lapua stopped making that brass......
 
I think you got a heck of a deal on an awesome cartridge in a great rifle. This cartridge is very effective. I was disappointed to hear you were considering rechambering right out of the gate.
For what it's worth, not only is brass still available for it, but my first two choices (American made) are both available.
Get some quality American made brass and go shoot that thing. I bet it would be awesome!
 
I am not familiar with the fps you can get out of a 6.5 -284 ,but the RPM is a burner and you can buy once fired brass from Weatherby for $1 a piece.Sometimes you have to wait awhile till they have some, but just get on the list!
