I don't think I would buy into the twist rate having much of anything to do with velocity loss in this case.
Every time I stumble into a 35 cal thread thread gunrunner8 is blathering on about pressure spikes and tight twist barrels. When confronted he has never dredged up a single piece of evidence that the effects he is so concerned about are anything more than completely negligible. I think we can all safely ignore his rather odd twist rate fetish.
