I finally managed to get some H-4350 to try in Caleb's rifle with the 165 BT. I also have some new Remington brass compliments of Rol_P. I first loaded a few rounds and shot them to measure velocities and water volume of the cases. Using that information I adjusted the QuickLoad program parameters and generated a Quickload projection.
Using the Quickload projection as a guide, I loaded up 9 rounds in .3 gr. increments. I tried to cover the range from a 22 " barrel OBT node 5 (1.127 ms) up to near maximum load (59,000 psi).
The results are shown below.
It appears that there is an accuracy node at 54.2 gr. (as predicted by QL). However, it is only at about 2690 ft./sec.
There may also be one at 55.4 gr. at about 2770 ft./sec.
I am trying to decide whether to load another batch in 0.2 gr. increments from 55.0 gr. to 56.4 gr. to verify a velocity plateau or just to load up some 55.4 gr. and shoot for a group.
I have say that I am very impressed by this relatively inexpensive Savage model 111. I may have to get one for myself...
