Greetings,
Those were the two projectiles I graphed, along with the old Hodgdon Data. The interesting thing was that the 160 grain partition was gaining pressure much faster than the 162 Hornady BTSP and would have got to 52,000 CUP well before the heavier projectile. I will certainly not be fiddling with high pressure loads in a 7mm Rem Mag as I don't have one. The 7mm SAUM I do have has data up to 65,000 PSI max rather than the 61,000 PSI max for the Rem Mag. The job for winter is to sort out loads for that and my heavy barrelled .223 for next seasons F Class shooting.
