picking up speed

[svandamme]

Got this from Vihtavuori's load tables



Test barrel: 150 mm (6"), 1 in 16" twist
Primers: Large Pistol
Cases: Remington, trim-to length 22.70 mm (.893"


14,9 230 FMJ-RN Hornady
gram grain m/s fps gram grain m/s fps
N340 0,38 5,9 253 830 0,41 6,4 278 912


12,0 185 TMJ-SWC Speer

N340 0,46 7,1 303 993 0,50 7,7 330 108


I'll start the 230's at 5.7
5 x 5.7
5 x 5.9
5 x 6.2

The SWC's at 195 grain
i'll batch those at 6.9

5x 6.9
5x 7.1
5x 7.3

Guess that should give me a good idea if i'm in the ball park.

I'm stayin .2 grain below the max load, don't feel like pushing the max unless i got good data on my lower loads first.. Gonna ask around in the club if anybody has a chronograph for validation... else order one..
