Hornady manual list cartridge over all length of 2.245 for 100 grain A-Max which is a pretty short bullet and needs to be seated a little deeper in most 6.5 Grendel barrels. I have to seat 95 grain V-Max at the same length (2.245) or the bullet will stick in the lands. I dumped a whole cartridge of powder in my lower trying to extract a V-Max which was seated to long in my first 6.5 Grendel AR-15.
Hodgdon list loading data with H-322 for Nosler 100 grain BT C.O.A.L. of 2.200.
Starting Load
Grains26.0
Velocity (ft/s)2,420
Pressure36,700 PSI
Maximum Load
Grains29.0C
Velocity (ft/s)2,716
Pressure49,800 PSI
Honestly I think the Hodgdon data is close enough to 100 grain A-Max I would start on the low end and work up using no more than .3 grain increase in powder charge.
Sounds like you and I thinking the same although Ive never used H-322 powder.
