loads for .300 win mag

[BIG BEAR]

Have been shooting 180gr.g c. ahead of H-4350 47 grains with great success in my .30-06. would like to try same 180s in my .300 mag. i would like to use the powders i have on hand , if possible, H-4350 and imr4831. have heard the HORROR stories about 4227 and shotgun powders. any help with loads using 4350 / 4831 would be great. thank you.

My only experiment with a long gone 300 win was 10 gr Unique and a Lee soup can. Accuracy was ok but not anywhere as good as it shot a 180 j word over 4831.
