Saatteko samankaltaisia tuloksia? Onko näillä tosiaan näin iso ero energiassa? -->

RK62, 13 gramman luoti ja 720 m/s... :shock:
No näillä arvoilla kyllä eroa energiassa on :drool: :wink:
Saatko tosiaan noin paljon vauhtia 13g kuulasta RKsta? Muistaakseni PVn normilataus 8g ja lähtöjä joku 700m/s pintaan.
Vertailu on laskettu D-166lla ja TAK-85:n arvoilla.
Otetaas pari grammaa luodista pois niin ollaan vähän lähempänä..
