Doesn't Keith's load assume Keith bullets as well? I'm almost positive that the crimp groove on most 250 grain Keith bullets is lower down on the bullet (ie, more bullet mass is outside the case when it's seated) compared to standard machine cast 240 grain SWCs (I'm thinking of Leadhead's .430 Keith bullets compared to the Lasercast SWC). This would give less pressure, and I wouldn't think the extra 10 grains of bullet weight on the Keith would be enough to cancel this out.
Leftoverdj, I'd be curious to hear your thoughts on that--you obviously have a lot more handloading experience than I, and I'm sort of pulling this theory out of you-know-where...
