Winchester 231 zero 124 9mm loads

[Flyboy]

Been looking at some load data for this combo. Can't find anything but generic bullets.
Looks like a starting point of 4.1 up to 4.4 on the powder. First loads here just wanting to cover everything?
Here is a load from Handloads.com

FMJ 4.5 gr Win 231 1,060 fps Winchester
Suggested starting load: 4.1 gr
Pressure: 32,700 PSI

Hodgdon site only list one load for a 124 FMJ gram bullet with wsf, and isnt specific on which bullet.

Thanks

One grain in bullet weight won't matter.  You can use load data for 124 or 125 grain bullets.  You can also use any data for the same TYPE of bullet.  You can load your Zero bullets with any data for 231/HP-38 with 124/125gr FMJ bullets, but not lead or plated data. 

 

This load from Hodgdon should do it.  I always use their data when it's available, other sources tend to be lower. 

125 GR. SIE FMJ  Hodgdon  HP-38  .355"  1.090"  4.4  1009  24,600 CUP  4.8  1088  28,800 CUP

The COL from Hodgdon is short with the 124gn Zero.  Set to what is free in barrel and feeds, but suspect 1.145" to 1.155" is a better COL.  I've loaded zero's with HP38 and HS6, but for 9mm with 124gr jacketed round nose loads I like 6.0 grains of AA #5 with a COL of 1.148"; mixed brass and primers.  For 9mm data, try this - http://www.mediafire.com/view/?7tgzoz0bqhx727u
