According to the online Hodgdon load data web site using those components 45.0gr compressed is the upper limit for H4350 and a 100gr Nosler BT, start (lowest) is listed as 40.5gr.
I was out doing load development today with 120gr SMK and Winchester 6.5 StaBALL, found a extremely accurate node (in the three's) at 44.7grs. What I did was look at max for the 6.5 StaBALL load listing back off 1.5grs start there went up 0.3grs increments until I found the node. AS I write this I'm pulling down the 120gr loaded with IMR4350 and switch over to the 6.5 StaBALL load. (COAL 2.753", CBTO=2.239").
