An SD of around 10fps will probably give you about 1 moa of vertical stringing/dispersion at 700 yards. You should be able to get an SD of around 15fps without getting too fancy with handloading. I just wanted to throw that out there if you're going to set goals for yourself.
Also, if you shoot at various ranges, you can calculate your MV to corroborate your chronograph. If you're consistently getting 1 moa at 700 yards, you know your approximate SD. Then if you observe your drop at 200, 300, 600, 700, you should be able to calculate a fairly accurate MV.
