300 win mag/ hornady / Remington

I have 5 full boxes. 2 boxes have the same arounds in it but in a different box there hornady 150 grain . I had to stick them into a different box . I lost the boxes because I had them in a hard box. But I kept the info of the original box for the proper info . sold the rifle and no longer need the ammo . Would like to trade for 270 wsm brass or loaded .  I need Winchester to keep it all the same . .277 bullets .
