Magnum is pretty slow for the 300 Win Mag with anything but the heaviest bullets and to working pressures. With bullets over 200 grains, it will likely work very well but stay on top of the carbon fouling and work your pressures up to near max loads for cleanest possible burn.
Have not used 4000mr so can not add anything there.
Third Generation Shooters Supply has one pound cans of H1000 instock and an 8 lb keg of H4831 in stock. In my opinion, both would probably be better then Ramshot Magnum.
