Keep in mind that you can go below the min, it may be wise to (for example start lower than min if you have a shorter OAl)
In 9mm I would say the absolute min (call it min 1)is enough powder to get the bullet out the barrel.
The real min (call it min 2)is enough to make you gun function 100% of the time.
Some cartridges you do have to worry about the min charge, IMO 9mm is not one of them
In 9mm I think you just need to worry about min(1), of course you will want to load to at least min(2).
Would need to search but I believe Walkalong did a test in 9mm to find "real" min charges. (what I call min 1 and min 2 above)
{If Walkalong is feeling kind (he usually is
) he may link it for me.}
Not 147s but
from Hodgdon/Win
125 FMJ Winchester WSF 0.355 1.16 4.7 1015 27,700 PSI 5.3 1115 32,700 PSI
My favorite match/plinking 125 PF 9mm load is 4.4-4.5gr WSF with a RMR 124 MPR at 1.09-1.10 (gives about 1030fps works out to 128 PF)
a shorter OAL and .3gr less than the "min/start" load-and higher vel that the 4.7gr start charge at the longer OAl.
At your short OAL the listed min/start charge for a longer OAL may be a MAX charge or more, don't get hung up on min/start, it is not a hard number just like the max is not a hard charge is not a hard number.
