7wsm

I am new here, Hi Guys! I had a question for you. I have Rem 700 5r milspec. It was .308. I had GA Precision re-chamber it for 300wsm. I had been thinking of re barreling it to 7mmx300wsm to take advantage of the high BC bullets. I have a bunch of 300wsm brass. whats the scoop on reloading...
