This is what I was going by ..
BULLET WEIGHT125 GR. HDY HAP
ManufacturerIMR
PowderSR 7625
Bullet Diameter.356"
C.O.L.1.069"
Starting Load
Grains3.3
Velocity (ft/s)804
Pressure25,600 PSI
Maximum Load
Grains3.8
Velocity (ft/s)914
Pressure32,000 PSI
I was at the 3.8 and with 1.069 oal with my test loads that did work out as they were the best for accuracy 1 inch at 20 yards.
So if I was to go to 1.10 C.O.L. what would a load to start with be 4.0 And work up from there ?
