I got my first press and above to start diving into reloading. I have found pretty good loads and have powder available for my .243 & 6.5CM but I'm on the search for "THE" powder for 175-190gr 300wm... I have H4350 I'm trying to trade that may work but what are the top 3 ideal powders for wide range temps? H4831 is what I'm looking at, Will H1000 work if I can get some or is that better suited for 200gr and up?
