[868s]

Tak for svaret; men mine målinger på 833 fps svarer til 260 m/s, og det er jo helt ude i hampen.

Hej 868s

Ja, QL siger 916m/s Når jeg har skudt med de små kalibre har QL også udregnet 30-50m/s for meget.

Ellers må du gå lidt ned i kuglevægt og skyde med f.eks Barnes kugle
der skal du nok få gennem skud alligevel.
