I just ordered a Remington 5R in 300 win today. This is my first time toying with the 300 win so I'm clueless. I've done some reloading for my 308 in the past, but nothing too crazy IE I never measured my lands or really refined a load for it.... But I definitely want to learn how to produce the most accurate round I can for this rifle via reloading. I have plans to shoot either Berger 215 VLD's or Hornady ELD-X 212s. As far as I could see, there weren't any factory loads with those bullets in them. So my question is this: with a brand new rifle, is it better to just pick up a couple of factory rounds of the heaviest bullet I can find and put them through the gun, sight it in, then use the fire formed brass to really dial a load then adjust my sights for heavier bullets once I reload? Or am I better off picking up empty brass, powder and bullets and going from there? If you think I should reload, any suggestions on powder and the best empty brass for the $ is appreciated!
