Data from the other day running a velocity profile for Stabal6.5 in a 6.5x55

OAT: 3* C/ 40 F & 97.6kpa (28.82 inhg)

Norma case, Murom kvb-7, Berger 130 VLD (moly)

Weight Vel (fps)
42gr 2534 (cold bore)
42gr 2520
43.5gr 2606
45gr 2676
46gr 2735
47gr 2855

No adverse pressure signs, no ejector marks at all, primers normal.

No groups but the 5" plate at 300 took a pummeling.

Use caution as usual. Hopefully this is a useful start for someone curious

I use Staball 6.5 for NRA Prone LR in a 6.5x47L (using 136Scenar, 140VLD’s). Based on posted scores, and firing experiences it is working out well for me.

My 6.5-Creedmoor reference load is with StaBall ... it's a little dirty, but very consistent and predictable. I can live with a 5.5 SD.

Follow up temp sensitivity data:

48gr Stabal6.5
130 Berger VLD moly
Norma brass
Murom primer

Temp (C) Velocity (fps) SD
-7 2899 18
28 2949 21

Average of 5 shots (sloppy with the loading/ holding today). Temp values may have an error of 3 deg or so, I didn't have the IR thermometer with me.

Slope of the line says temp sensitivity is somewhere around 1.22 fps/ deg C (about 0.71 fps/deg F)
