jwall,

If you already have a good stock of IMR 4350, 4831, and 7828 you have the range of powders you need (although you could also use 4064 if going for a lightweight 85-100g load). IMR 4350 was the first powder I ever tried in my 6.5x55 and it worked great with a 140g Hornady SP. I've never used IMR 4831 and only dabbled with 7828 SSC in the 6.5x55. But there is enough data out there with the "old standby" powders to get you what you want.

But, my answer to your original question about my favorite powder in the 6.5x55 is still Reloder 22.

Good luck!
