....give me an approximate velocity for the following .308 load?
Lapua Lockbase FMJBT 170gn
Norma case
Fiocchi LR primer
N140 44.0gn
OAL 72.35mm (no crimp)
CZ550 25.6" barrel. (shooting suppressed if possible)
I'm trying to guess the velocity for trajectory purposes as I'm shooting at 600m in two weeks (a first for me) and probably won't get a chance to chrono before then.
On the day, what you can take and do will be pretty tightly controlled as I think there will be many shooters, so holding everyone up while I set up, adjust, use and remove my tripod and chrono would not go down well.
My guesstimates based on Lapua load data (24") says about 2600fps, so perhaps up to 2700 in my longer barrel.
Thanks in advance.
