Mono performance at 7mag, 7 rum etc, etc. are of no consequence to what he asked for....
Well not entirely, as long as people supply enough useful information like MV and Impact vel. for the type of bullet,
e.g.; someone takes their animal at 350yd with a 7mm mag, its very close to same impact velocity for 7mm/08 at 150yd.
so a person can sensibly reckon from there.
