Hjælp til .338 WM-ladning

[KSB]

Jeg søger ladedata til en fladtskydende (og naturligvis præcis) .338 WM-ladning.

Jeg har søgt flere steder på nettet, men har ikke kunnet finde noget som har den samme krudt&kugle-konfiguration, som jeg ønsker.

Ladningen skal baseres på:

Hylster: Norma
Kugle: Barnes TTSX 185 gr.
Krudt: Vihta. N160
Primer: CCI 250 Mag
COAL: ca. 83,3 mm
Pibelængde: 650 mm (SL 97 DL)
