I do start at minimum and I do consider that it may be close to max, but it seems to me that a total case separation at minimum charge is beyond what one should reasonably expect.
For me the bigger issue is the discrepancy between the online data and my reloading manuals.
A few grains difference does not surprise me at all but as I said, I found several loads for a number of different calibers where Hodgdon's data started where my manuals stopped.
And some of those loads in the manuals are loads I had used in working up loads for other rifles in the past.
A bad batch of powder makes more sense to me then anything else.
