Clays is really touchy over the max and has blown up more than it's share of guns. Loading long is a good precaution. Working past the max is not a good idea because it's pressure curve is very non-linear. It is also prone to pressure spikes. There is a reason why there is not much load data with bullets over 124 gr in 9mm.

Try to find some better data with a longer OAL, drop to a lighter bullet or find a more suitable powder.
