Velocity data - 6 BR Norma

[camoscio]

Hy
My Chrony doesen't work and I can' measure my loads speed.
Actually I shot SMK107 Moly with 30.5 grs. of N140 or 31.5 grs of N150,bullet seated 0.03 out of the lands) and the same charges for Bergers VLD 105 Moly,free boring zero).
My barel is 24.6' anybody can indicate me the velocity +/- of that loads ?
Sorry for my english

Ciao from Italy

2709fps for Moly 107; 2772fps for VLD. These are very rough guesses since you di not list your MAX COAL. Don't know where the lands really are. Seating depts make a large difference in PRESSURE and velocity.

Again, these are rough guesses.
