None that I can back up with hard data. I will say that I extrapolated a start load for this 70 grainer last week based on start data for 2400 and a 55 gr. boolit and I was way off and ended up with a sticky bolt in my 788, which is not hard with the design. Therefore I am hesitant to make any direct comparisons with 2400. I should have a replacement chrono in the next couple of weeks so I should be able to have some better data. I would also add that the 8 gr. Steel and the 70 gr. NOE gave me nice rounded primers.
