Haley Scandalous, initial fill pressures and bore dimensions
I did about all I could today considering I did not have that stock as of yet.
I slugged the bore, it slugged out at .257.
I tested for fill pressures by filling to 3500 PSI and shooting one shot over the chrony and then repeating every 200 PSI unti velocity quit increasing, then I shot a strig with the 74 grain bullets and the 94 grain bullets. It was hard to keep it level over the chrony without a scope and holding the action, the speeds may in fact be a little faster if I had it perfectly level.
74 grains
3500 PSI=1074 FPS
3700 PSI=1096 FPS
3900 PSI=1100 FPS
4100 PSI=1088-1101-1083-1042
1101 is right around 200 FPE
94 grains
4200=970 FPS-1028-1005
top FPE is right around 220 FPE
Jack is sending out some more springs to raise the opening pressure.
And I am leaving to look for that stock at the PO.
