    Default Can somebody explain to me correct ballistics?

    I was researching handloads for 7mm08 and found one that claimed a 150 grn swift scirrocco loaded to 2780 fps and zeroed at 200yds was 1 3/4" low at 300yds. My ballistic chart says it should be -8.48 . ***! Anybody have an answer to that? Which is more probable? I haven't had a chance to verify myself.

    According to Load from a Disk,,,, Minus 7.73, using those figures, and the BC of that bullet, (.515)

    Sounds like a typo. Perhaps they meant -7.75" instead of -1.75"

    could also be a typo on the front end as zeroed at + 1.75 at 100 would be about right for dead on at 200....
