Hodgdon has load data on their website for powder for 130's. For the 140 BT they are showing 2.880 for seating. Do your own research/don't trust me but I've been told the BT and accubond have the same profile. The 2.880 seating has worked well for me thus far with H1000. Other than that, Hornday has data for 140-147 grain. And as above, you can email Sierra and ask for the data for the PRC.
