If possible, I'd need an indication for Muzzle V/0 from two loads I am currently using.

Barrel is a 6,5x57 RIMMED - 24" length and 1 in 8" twist rate

Load 1 : RWS Brass - Nosler Ball.Tip 120 grs bullet - CCI Br2 primers - Norma 204 powder x 46 grs. - COAL 78,60 mm. (3,09")

Load 2 : RWS Brass - Lapua Scenar 139 grs bullet - CCI Br2 primers - Norma 204 powder x 45 grs. - COAL 80,90 mm. (3,18")

If needed....
