some of the 9 twist remmy 204's shoot 32 gr v-max's incredibly well. my 8 twist 6.5 gibbs does way better than good with 95 gr v-max's. I always twist a rifle one step faster than I know I need to shoot the bullet that I've planned for.

I definitely agree, if the bullet can take it, I want it spinning as fast as I can. I've never personally pushed one hard enough to frag out of the muzzle. I've ran down to 40grn bullets in a 1 in 8" .223 AI and haven't seen one pop yet (crappy accuracy from excessive throat jump, should have seen that coming
).
I suppose I could believe an over-spun bullet would foul more than a "normally" stabilized bullet, but I don't know that it'd be significantly MORE difference in fouling than the difference between a poor quality barrel, or too soft of bullets, etc etc.
