[QUOTE="Bart B, post: 656846, member: 5302"] When the .300 WM was popular for long range matches fired in the prone position. IMR4350 was the favorite for accuracy. And it worked fine with standard primers; magnum ones aren't needed unless you're after animals in sub freezing weather. While slower powders will usually shoot a given bullet out faster, those bullets won't land as close together on target as the medium-slow ones get such as IMR4350. Don't use any ball powder if best accuracy's your goal. I believe Sierra Bullets still uses IMR4350 in their .300 Win. Mag. cases testing 30 caliber bullets weighing 190 grains and heavier for accuracy as shot from super accurate rail guns. [/QUOTE]
