[QUOTE="bbutturff, post: 553466, member: 31436"] I had this same conversation with a friend last June. He always uses CCI200s in his 300 RUM and I always use CCI250s in my 300 WSM. Just for grins we swapped a hundred. He claims his MV went up 150-200 fps and his ES went down simply by using the hotter 250s. I don't know what powder he uses in this load but it's safe to say it's one of the magnum powders. I haven't tried the 200s in any of my pet loads yet but I would expect to see a difference. [/QUOTE]
